You are given N integer sequences A1, A2, ..., AN. Each of these sequences contains N elements. You should pick N elements, one from each sequence; let's denote the element picked from sequence Ai by Ei. For each i (2 ≤ i ≤ N), Ei should be strictly greater than Ei-1.
Compute the maximum possible value of E1 + E2 + ... + EN. If it's impossible to pick the elements E1, E2, ..., EN, print -1 instead.

-----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.
- N lines follow. For each valid i, the i-th of these lines contains N space-separated integers Ai1, Ai2, ..., AiN denoting the elements of the sequence Ai.

-----Output-----
For each test case, print a single line containing one integer — the maximum sum of picked elements.

-----Constraints-----
- 1 ≤ T ≤ 10
- 1 ≤ N ≤ 700
- 1 ≤ sum of N in all test-cases ≤ 3700
- 1 ≤ Aij ≤ 109 for each valid i, j

-----Subtasks-----
Subtask #1 (18 points): 1 ≤ Aij ≤ N for each valid i, j
Subtask #2 (82 points): original constraints

-----Example-----
Input:

1
3
1 2 3
4 5 6
7 8 9

Output:

18

-----Explanation-----
Example case 1: To maximise the score, pick 3 from the first row, 6 from the second row and 9 from the third row. The resulting sum is E1+E2+E3 = 3+6+9 = 18.

Toad Rash has a binary string $s$. A binary string consists only of zeros and ones.

Let $n$ be the length of $s$.

Rash needs to find the number of such pairs of integers $l$, $r$ that $1 \leq l \leq r \leq n$ and there is at least one pair of integers $x$, $k$ such that $1 \leq x, k \leq n$, $l \leq x < x + 2k \leq r$, and $s_x = s_{x+k} = s_{x+2k}$.

Find this number of pairs for Rash.


-----Input-----

The first line contains the string $s$ ($1 \leq |s| \leq 300\,000$), consisting of zeros and ones.


-----Output-----

Output one integer: the number of such pairs of integers $l$, $r$ that $1 \leq l \leq r \leq n$ and there is at least one pair of integers $x$, $k$ such that $1 \leq x, k \leq n$, $l \leq x < x + 2k \leq r$, and $s_x = s_{x+k} = s_{x+2k}$.


-----Examples-----
Input
010101

Output
3

Input
11001100

Output
0



-----Note-----

In the first example, there are three $l$, $r$ pairs we need to count: $1$, $6$; $2$, $6$; and $1$, $5$.

In the second example, there are no values $x$, $k$ for the initial string, so the answer is $0$.

Eugene loves sequences, especially arithmetic progressions. One day he was asked to solve a difficult problem.

If a sequence of numbers A1, A2, ... , AN form an arithmetic progression A, he was asked to calculate sum of F(Ai), for L ≤ i ≤ R.
F(X) is defined as:

If X < 10 then F(X) = X.

Else F(X) = F(sum_of_digits(X)).

Example:
F(1378) = 
F(1+3+7+8) = 
F(19) = 
F(1 + 9) = 
F(10) = 
F(1+0) = 
F(1) = 1

-----Input-----
- The first line of the input contains an integer T denoting the number of test cases.
- Each test case is described in one line containing four integers: A1 denoting the first element of the arithmetic progression A, D denoting the common difference between successive members of A, and L and R as described in the problem statement.

-----Output-----
- For each test case, output a single line containing one integer denoting sum of F(Ai).

-----Constraints-----
- 1 ≤ T ≤ 105
- 1 ≤ A1 ≤ 109
- 0 ≤ D ≤ 109
- 1 ≤ R ≤ 1018
- 1 ≤ L ≤ R

-----Subtasks-----
- Subtask 1:  0 ≤ D ≤ 100, 1 ≤ A1 ≤ 109, 1 ≤ R ≤ 100  - 15 points
- Subtask 2:  0 ≤ D ≤ 109, 1 ≤ A1 ≤ 109, 1 ≤ R ≤ 106  - 25 points
- Subtask 3: Original constraints - 60 points

-----Example-----
Input:
2
1 1 1 3
14 7 2 4

Output:
6
12

-----Explanation-----
Example case 1.
A = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, ...}
A1 = 1

You are given an array a with n distinct integers. Construct an array b by permuting a such that for every non-empty subset of indices S = {x_1, x_2, ..., x_{k}} (1 ≤ x_{i} ≤ n, 0 < k < n) the sums of elements on that positions in a and b are different, i. e. $\sum_{i = 1}^{k} a_{x_{i}} \neq \sum_{i = 1}^{k} b_{x_{i}}$


-----Input-----

The first line contains one integer n (1 ≤ n ≤ 22) — the size of the array.

The second line contains n space-separated distinct integers a_1, a_2, ..., a_{n} (0 ≤ a_{i} ≤ 10^9) — the elements of the array.


-----Output-----

If there is no such array b, print -1.

Otherwise in the only line print n space-separated integers b_1, b_2, ..., b_{n}. Note that b must be a permutation of a.

If there are multiple answers, print any of them.


-----Examples-----
Input
2
1 2

Output
2 1 

Input
4
1000 100 10 1

Output
100 1 1000 10



-----Note-----

An array x is a permutation of y, if we can shuffle elements of y such that it will coincide with x.

Note that the empty subset and the subset containing all indices are not counted.

You are fishing with polar bears Alice and Bob. While waiting for the fish to bite, the polar bears get bored. They come up with a game. First Alice and Bob each writes a 01-string (strings that only contain character "0" and "1") a and b. Then you try to turn a into b using two types of operations:  Write parity(a) to the end of a. For example, $1010 \rightarrow 10100$.  Remove the first character of a. For example, $1001 \rightarrow 001$. You cannot perform this operation if a is empty. 

You can use as many operations as you want. The problem is, is it possible to turn a into b?

The parity of a 01-string is 1 if there is an odd number of "1"s in the string, and 0 otherwise.


-----Input-----

The first line contains the string a and the second line contains the string b (1 ≤ |a|, |b| ≤ 1000). Both strings contain only the characters "0" and "1". Here |x| denotes the length of the string x.


-----Output-----

Print "YES" (without quotes) if it is possible to turn a into b, and "NO" (without quotes) otherwise.


-----Examples-----
Input
01011
0110

Output
YES

Input
0011
1110

Output
NO



-----Note-----

In the first sample, the steps are as follows: 01011 → 1011 → 011 → 0110

Hooray! Polycarp turned $n$ years old! The Technocup Team sincerely congratulates Polycarp!

Polycarp celebrated all of his $n$ birthdays: from the $1$-th to the $n$-th. At the moment, he is wondering: how many times he turned beautiful number of years?

According to Polycarp, a positive integer is beautiful if it consists of only one digit repeated one or more times. For example, the following numbers are beautiful: $1$, $77$, $777$, $44$ and $999999$. The following numbers are not beautiful: $12$, $11110$, $6969$ and $987654321$.

Of course, Polycarpus uses the decimal numeral system (i.e. radix is 10).

Help Polycarpus to find the number of numbers from $1$ to $n$ (inclusive) that are beautiful.


-----Input-----

The first line contains an integer $t$ ($1 \le t \le 10^4$) — the number of test cases in the input. Then $t$ test cases follow.

Each test case consists of one line, which contains a positive integer $n$ ($1 \le n \le 10^9$) — how many years Polycarp has turned.


-----Output-----

Print $t$ integers — the answers to the given test cases in the order they are written in the test. Each answer is an integer: the number of beautiful years between $1$ and $n$, inclusive.


-----Example-----
Input
6
18
1
9
100500
33
1000000000

Output
10
1
9
45
12
81



-----Note-----

In the first test case of the example beautiful years are $1$, $2$, $3$, $4$, $5$, $6$, $7$, $8$, $9$ and $11$.

-----General Statement:-----
Read a number in scientific notation and output its equivalent decimal value.

-----Input:-----
All data is on a single line. The first integer indicates how many pairs of numbers follow. The first of each pair is A, the base number, and the second is E, the power of 10.

-----Output:-----
Round each answer to 2 decimal places. Trailing zeros to the right of the decimal point are required. A leading zero to the left of the decimal point is not required.
The output is to be formatted exactly like that for the sample output given below.

-----Assumptions:-----
E is in the range –10 .. 10. A is 1 or larger but less than 10.
Discussion: 
If A = 3.926 and E = 4, the number represented is 3.926 X 104 or 39260, which is 39260.00 when rounded to 2 decimal places.

-----Sample Input:-----
4 4.296 3 3.8 -2 1.8 2 2.8678 1

-----Sample Output:-----
4296.00
0.04
180.00
28.68
