The statement of this problem is the same as the statement of problem C2. The only difference is that, in problem C1, $n$ is always even, and in C2, $n$ is always odd.

You are given a regular polygon with $2 \cdot n$ vertices (it's convex and has equal sides and equal angles) and all its sides have length $1$. Let's name it as $2n$-gon.

Your task is to find the square of the minimum size such that you can embed $2n$-gon in the square. Embedding $2n$-gon in the square means that you need to place $2n$-gon in the square in such way that each point which lies inside or on a border of $2n$-gon should also lie inside or on a border of the square.

You can rotate $2n$-gon and/or the square.


-----Input-----

The first line contains a single integer $T$ ($1 \le T \le 200$) — the number of test cases.

Next $T$ lines contain descriptions of test cases — one per line. Each line contains single even integer $n$ ($2 \le n \le 200$). Don't forget you need to embed $2n$-gon, not an $n$-gon.


-----Output-----

Print $T$ real numbers — one per test case. For each test case, print the minimum length of a side of the square $2n$-gon can be embedded in. Your answer will be considered correct if its absolute or relative error doesn't exceed $10^{-6}$.

Find the minimum area of a square land on which you can place two identical rectangular $a \times b$ houses. The sides of the houses should be parallel to the sides of the desired square land.

Formally,   You are given two identical rectangles with side lengths $a$ and $b$ ($1 \le a, b \le 100$) — positive integers (you are given just the sizes, but not their positions).  Find the square of the minimum area that contains both given rectangles. Rectangles can be rotated (both or just one), moved, but the sides of the rectangles should be parallel to the sides of the desired square. 

Two rectangles can touch each other (side or corner), but cannot intersect. Rectangles can also touch the sides of the square but must be completely inside it. You can rotate the rectangles. Take a look at the examples for a better understanding.

 [Image] The picture shows a square that contains red and green rectangles. 


-----Input-----

The first line contains an integer $t$ ($1 \le t \le 10\,000$) —the number of test cases in the input. Then $t$ test cases follow.

Each test case is a line containing two integers $a$, $b$ ($1 \le a, b \le 100$) — side lengths of the rectangles.


-----Output-----

Print $t$ answers to the test cases. Each answer must be a single integer — minimal area of square land, that contains two rectangles with dimensions $a \times b$.

Gru has not been in the limelight for a long time and is, therefore, planning something particularly nefarious. Frustrated by his minions' incapability which has kept him away from the limelight, he has built a transmogrifier — a machine which mutates minions.

Each minion has an intrinsic characteristic value (similar to our DNA), which is an integer. The transmogrifier adds an integer K to each of the minions' characteristic value. 

Gru knows that if the new characteristic value of a minion is divisible by 7, then it will have Wolverine-like mutations.

Given the initial characteristic integers of N minions, all of which are then transmogrified, find out how many of them become Wolverine-like.

-----Input Format:-----
The first line contains one integer, T, which is the number of test cases. Each test case is then described in two lines.
The first line contains two integers N and K, as described in the statement.
The next line contains N integers, which denote the initial characteristic values for the minions.

-----Output Format:-----
For each testcase, output one integer in a new line, which is the number of Wolverine-like minions after the transmogrification.

-----Constraints:-----
- 1 ≤ T ≤ 100
- 1 ≤ N ≤ 100
- 1 ≤ K ≤ 100
- All initial characteristic values lie between 1 and 105, both inclusive.

-----Example-----
Input:
1
5 10
2 4 1 35 1

Output:
1

-----Explanation:-----
After transmogrification, the characteristic values become {12,14,11,45,11}, out of which only 14 is divisible by 7. So only the second minion becomes Wolverine-like.

Chef and his competitor Kefa own two restaurants located at a straight road. The position of Chef's restaurant is $X_1$, the position of Kefa's restaurant is $X_2$.
Chef and Kefa found out at the same time that a bottle with a secret recipe is located on the road between their restaurants. The position of the bottle is $X_3$.
The cooks immediately started to run to the bottle. Chef runs with speed $V_1$, Kefa with speed $V_2$.
Your task is to figure out who reaches the bottle first and gets the secret recipe (of course, it is possible that both cooks reach the bottle at the same time).

-----Input-----
- The first line of the input contains a single integer $T$ denoting the number of test cases. The description of $T$ test cases follows.
- The first and only line of each test case contains five space-separated integers $X_1$, $X_2$, $X_3$, $V_1$ and $V_2$. 

-----Output-----
For each test case, print a single line containing the string "Chef" if Chef reaches the bottle first, "Kefa" if Kefa reaches the bottle first or "Draw" if Chef and Kefa reach the bottle at the same time (without quotes). 

-----Constraints-----
- $1 \le T \le 10^5$
- $|X_1|, |X_2|, |X_3| \le 10^5$

"I don't have any fancy quotes." - vijju123
Chef was reading some quotes by great people. Now, he is interested in classifying all the fancy quotes he knows. He thinks that all fancy quotes which contain the word "not" are Real Fancy; quotes that do not contain it are regularly fancy.
You are given some quotes. For each quote, you need to tell Chef if it is Real Fancy or just regularly fancy.

-----Input-----
- The first line of the input contains a single integer $T$ denoting the number of test cases. The description of $T$ test cases follows.
- The first and only line of each test case contains a single string $S$ denoting a quote.

-----Output-----
For each test case, print a single line containing the string "Real Fancy" or "regularly fancy" (without quotes).

=====Function Descriptions=====
group()

A group() expression returns one or more subgroups of the match.
Code

>>> import re
>>> m = re.match(r'(\w+)@(\w+)\.(\w+)','username@hackerrank.com')
>>> m.group(0)       # The entire match 
'username@hackerrank.com'
>>> m.group(1)       # The first parenthesized subgroup.
'username'
>>> m.group(2)       # The second parenthesized subgroup.
'hackerrank'
>>> m.group(3)       # The third parenthesized subgroup.
'com'
>>> m.group(1,2,3)   # Multiple arguments give us a tuple.
('username', 'hackerrank', 'com')

groups()

A groups() expression returns a tuple containing all the subgroups of the match.
Code

>>> import re
>>> m = re.match(r'(\w+)@(\w+)\.(\w+)','username@hackerrank.com')
>>> m.groups()
('username', 'hackerrank', 'com')

groupdict()

A groupdict() expression returns a dictionary containing all the named subgroups of the match, keyed by the subgroup name.
Code

>>> m = re.match(r'(?P<user>\w+)@(?P<website>\w+)\.(?P<extension>\w+)','myname@hackerrank.com')
>>> m.groupdict()
{'website': 'hackerrank', 'user': 'myname', 'extension': 'com'}

=====Problem Statement=====
You are given a string S.
Your task is to find the first occurrence of an alphanumeric character in (read from left to right) that has consecutive repetitions. 

=====Input Format=====
A single line of input containing the string S.

=====Constraints=====
0<len(S)<100

=====Output Format=====
Print the first occurrence of the repeating character. If there are no repeating characters, print -1.

Jack really likes his number five: the trick here is that you have to multiply each number by 5 raised to the number of digits of each numbers, so, for example:
```python
multiply(3)==15
multiply(10)==250
multiply(200)==25000
multiply(0)==0
multiply(-3)==-15
```

Little chef has just been introduced to the world of numbers! While experimenting with addition and multiplication operations, the little chef came up with the following problem:

Given an array A of non-negative integers, how many pairs of indices i and j exist such that  A[i]*A[j] > A[i]+A[j]  where  i < j .

Now being a learner, little chef isn't able to solve this problem efficiently and hence turns to you for help. 

-----Input-----
First line of input contains an integer T denoting the number of test cases. For each test case, the first line contains an integer N denoting the number of integers in the array. The next line contains N space separated integers where the ith integer represents A[i]. 
Note : There may be trailing spaces on each line of input. 

-----Output-----
For each test, print the required number of pairs in a single line.

-----Constraints-----
-  1 ≤ T ≤ 10 
-  2 ≤ N ≤ 100000 (105) 
-  0 ≤ A[i] ≤ 1000000 (106)

-----Example-----
Input:
2
3
3 4 5
4
1 1 1 1

Output:
3
0

-----Explanation-----

Example case 1.

All pairs of numbers satisfy the criteria. Total number of pairs equals 3.

Example case 2.

No pair of numbers satisfy the criteria.

Chef made $N$ pieces of cakes, numbered them $1$ through $N$ and arranged them in a row in this order. There are $K$ possible types of flavours (numbered $1$ through $K$); for each valid $i$, the $i$-th piece of cake has a flavour $A_i$.
Chef wants to select a contiguous subsegment of the pieces of cake such that there is at least one flavour which does not occur in that subsegment. Find the maximum possible length of such a subsegment of cakes.

-----Input-----
- The first line of the input contains a single integer $T$ denoting the number of test cases. The description of $T$ test cases follows.
- The first line of each test case contains two integers $N$ and $K$.
- The second line contains $N$ space-separated integers $A_1, A_2, \ldots, A_N$.

-----Output-----
For each test case, print a single line containing one integer ― the maximum length of a valid subsegment.

-----Constraints-----
- $1 \le T \le 1,000$
- $1 \le N \le 10^5$
- $2 \le K \le 10^5$
- $1 \le A_i \le K$ for each valid $i$
- the sum of $N$ over all test cases does not exceed $10^6$

-----Subtasks-----
Subtask #1 (50 points):
- $N \le 10^3$
- $K = 2$
- the sum of $N$ over all test cases does not exceed $10^4$
Subtask #2 (50 points): original constraints

A permutation p of size n is the sequence p_1, p_2, ..., p_{n}, consisting of n distinct integers, each of them is from 1 to n (1 ≤ p_{i} ≤ n).

A lucky permutation is such permutation p, that any integer i (1 ≤ i ≤ n) meets this condition p_{p}_{i} = n - i + 1.

You have integer n. Find some lucky permutation p of size n.


-----Input-----

The first line contains integer n (1 ≤ n ≤ 10^5) — the required permutation size.


-----Output-----

Print "-1" (without the quotes) if the lucky permutation p of size n doesn't exist.

Otherwise, print n distinct integers p_1, p_2, ..., p_{n} (1 ≤ p_{i} ≤ n) after a space — the required permutation.

If there are multiple answers, you can print any of them.

Let's denote as $\text{popcount}(x)$ the number of bits set ('1' bits) in the binary representation of the non-negative integer x.

You are given multiple queries consisting of pairs of integers l and r. For each query, find the x, such that l ≤ x ≤ r, and $\text{popcount}(x)$ is maximum possible. If there are multiple such numbers find the smallest of them.


-----Input-----

The first line contains integer n — the number of queries (1 ≤ n ≤ 10000).

Each of the following n lines contain two integers l_{i}, r_{i} — the arguments for the corresponding query (0 ≤ l_{i} ≤ r_{i} ≤ 10^18).


-----Output-----

For each query print the answer in a separate line.


-----Examples-----
Input
3
1 2
2 4
1 10

Output
1
3
7



-----Note-----

The binary representations of numbers from 1 to 10 are listed below:

1_10 = 1_2

2_10 = 10_2

3_10 = 11_2

4_10 = 100_2

5_10 = 101_2

6_10 = 110_2

7_10 = 111_2

8_10 = 1000_2

9_10 = 1001_2

10_10 = 1010_2

Master Shifu is training Po to become The Dragon Warrior and as a final assignment he must obtain maximum deliciousness from dumplings. There are  $N$ plates of dumplings in front of him with deliciousness $A_1, A_2, \ldots, A_N$, Po can choose any number of continuous plates of  dumplings. The total deliciousness is the sum of deliciousness of all the  chosen dumplings.
What is the minimum number of plates he must choose so that total deliciousness is maximum possible?
Note: Po must choose atleast one plate.

-----Input:-----
- The first line of the input contains a single integer $T$ denoting the number of test cases. The description of $T$ test cases follows.
- The first line of each test case contains a single integer $N$.
- The second line contains $N$ space-separated integers $A_1, A_2, \ldots, A_N$.

-----Output:-----
For each test case, print a single line containing one integer.
