A permutation $p_1,p_2...p_N$ of $\{1, 2, ..., N\}$ is beautiful if $p_i \& p_{i+1}$ is greater than 0 for every $1 \leq i < N$ . You are given an integer $N$, and your task is toconstruct a beautiful permutation of length $N$ or determine that it's impossible.
Note that $a \& b$ denotes the bitwise AND of $a$ and $b$.

-----Input:-----
First line will contain $T$, number of testcases. Then the testcases follow. 
Each testcase contains a single line of input, an integer $N$.

-----Output:-----
For each test case output $-1$ if there is no suitable permutation of length $N$, otherwise output $N$ integers in a single line which form a beautiful permutation. If there are multiple answers output any of them.

-----Constraints-----
- $1 \leq N \leq 10^5$
- The sum of $N$ over all test cases does not exceed $10^6$

-----Subtasks-----
- 50 points : $1 \leq N,T \leq 9$
- 50 points : Original constraints

-----Sample Input:-----
3

-----Sample Output:-----

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-----
- $1 \le T \le 10^5$
- $|X_1|, |X_2|, |X_3| \le 10^5$
- $X_1 < X_3 < X_2$
- $1 \le V_1 \le 10^5$
- $1 \le V_2 \le 10^5$

-----Example Input-----
3
1 3 2 1 2
1 5 2 1 2
1 5 3 2 2

-----Example Output-----
Kefa
Chef
Draw

-----Explanation-----
Example case 1. Chef and Kefa are on the same distance from the bottle, but Kefa has speed $2$, while Chef has speed $1$.

You are given a string S of length n with each character being one of the first m lowercase English letters. 

Calculate how many different strings T of length n composed from the first m lowercase English letters exist such that the length of LCS (longest common subsequence) between S and T is n - 1.

Recall that LCS of two strings S and T is the longest string C such that C both in S and T as a subsequence.


-----Input-----

The first line contains two numbers n and m denoting the length of string S and number of first English lowercase characters forming the character set for strings (1 ≤ n ≤ 100 000, 2 ≤ m ≤ 26).

The second line contains string S.


-----Output-----

Print the only line containing the answer.


-----Examples-----
Input
3 3
aaa

Output
6

Input
3 3
aab

Output
11

Input
1 2
a

Output
1

Input
10 9
abacadefgh

Output
789



-----Note-----

For the first sample, the 6 possible strings T are: aab, aac, aba, aca, baa, caa. 

For the second sample, the 11 possible strings T are: aaa, aac, aba, abb, abc, aca, acb, baa, bab, caa, cab.

For the third sample, the only possible string T is b.

In this Kata we are passing a number (n) into a function. 

Your code will determine if the number passed is even (or not). 

The function needs to return either a true or false. 

Numbers may be positive or negative, integers or floats.

Floats are considered UNeven for this kata.

Akshay is interested in mathematics, one day he came across a problem of modulus operator.He has  a list of M integers say arr[M] and has to find all integers K such that :
- K > 1
- arr[1]%K = arr[2]%K = arr[3]%K = … = arr[M]%K where '%' is a modulus operator.
Help Akshay to find all such K's.

-----Input:-----
- First line of input contains an integer M. Then M lines follow each containing one integer of the list. Input data is such that at least one integer K will always exist.

-----Output:-----
- Output all possible integers K separated by space in increasing order.

-----Constraints-----
- 2<= M <=100
- 1< value of each integer <109
- All integers will be distinct

-----Sample Input:-----
3
38
6

-----Sample Output:-----

You are given two positive integers N and K. How many multisets of rational numbers satisfy all of the following conditions?
 - The multiset has exactly N elements and the sum of them is equal to K.
 - Each element of the multiset is one of 1, \frac{1}{2}, \frac{1}{4}, \frac{1}{8}, \dots. In other words, each element can be represented as \frac{1}{2^i}\ (i = 0,1,\dots).
The answer may be large, so print it modulo 998244353.

-----Constraints-----
 - 1 \leq K \leq N \leq 3000
 - All values in input are integers.

-----Input-----
Input is given from Standard Input in the following format:
N K

-----Output-----
Print the number of multisets of rational numbers that satisfy all of the given conditions modulo 998244353.

-----Sample Input-----
4 2

-----Sample Output-----
2

The following two multisets satisfy all of the given conditions:
 - {1, \frac{1}{2}, \frac{1}{4}, \frac{1}{4}}
 - {\frac{1}{2}, \frac{1}{2}, \frac{1}{2}, \frac{1}{2}}

The chef is having one array of natural numbers. Cheffina challenges chef that find the sum of weights all the natural numbers present in the array, but the main problem is that all numbers have not original weights. After every 6 natural numbers weight is set to 1 as weight increases by 1 after that. (i.e. weight of 1 is 1, weight of 2 is 2 but the weight of 7 is 1 and weight of 8 is 2 and so on…). Help the chef to find the sum. 

-----Input:-----
- First line will contain $T$, number of testcases. Then the testcases follow. 
- Each testcase contains two lines of input, one integer $N$.
- Next line has N space separate natural numbers. 

-----Output:-----
For each testcase, output in a single line answer.

-----Constraints-----
- $1 \leq T \leq 10$
- $1 \leq N \leq 10^5$
- $1 \leq arr[i] \leq 10^6$

-----Sample Input:-----
1
6
6 7 9 11 4 16

-----Sample Output:-----
23

-----EXPLANATION:-----
Array after conversion = [6, 1, 3, 5, 4, 4]

Chef is playing a game with two of his friends. In this game, each player chooses an integer between $1$ and $P$ inclusive. Let's denote the integers chosen by Chef, friend 1 and friend 2 by $i$, $j$ and $k$ respectively; then,  Chef's score is
(((Nmodi)modj)modk)modN.(((Nmodi)modj)modk)modN.(((N\,\mathrm{mod}\,i)\,\mathrm{mod}\,j)\,\mathrm{mod}\,k)\,\mathrm{mod}\,N\,.

Chef wants to obtain the maximum possible score. Let's denote this maximum score by $M$. Find the number of ways to choose the triple $(i,j,k)$ so that Chef's score is equal to $M$.

-----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 two space-separated integers $N$ and $P$.

-----Output-----
For each test case, print a single line containing one integer — the number of ways to obtain the maximum score.

-----Constraints-----
- $1 \le T \le 10^6$
- $1 \le N \le P \le 10^6$

-----Subtasks-----
Subtask #1 (10 points):
- $1 \le T \le 100$
- $1 \le N \le P \le 100$
Subtask #2 (90 points): original constraints

-----Example Input-----
2
4 4
3 4

-----Example Output-----
9
13

-----Explanation-----
Example case 1: Chef's maximum possible score is $M = 1$. All possible values of $(i, j, k)$ such that the score is $1$ are
$(3, 2, 2)$,
$(3, 2, 3)$,
$(3, 2, 4)$,
$(3, 3, 2)$,
$(3, 3, 3)$,
$(3, 3, 4)$,
$(3, 4, 2)$,
$(3, 4, 3)$,
$(3, 4, 4)$.
