You are given an array with $N$ integers: $A[1], A[2], \ldots, A[N]$ (where $N$ is even). You are allowed to permute the elements however you want. Say, after permuting the elements, you end up with the array $A'[1], A'[2], \ldots, A'[N]$. Your goal is to maximize the following sum:
|A′[1]−A′[2]| + |A′[3]−A′[4]| + ... + |A′[N−1]−A′[N]||A′[1]−A′[2]| + |A′[3]−A′[4]| + ... + |A′[N−1]−A′[N]|
|A'[1] - A'[2]| \ + \ |A'[3] - A'[4]| \ + \ ... \ + \ |A'[N - 1] - A'[N]|

Here, $|x|$ denotes the absolute value of $x$.
You have to print the maximum sum achievable.

-----Input-----
- The first line contains $T$, the number of test cases.
- Each test case starts with an integer $N$ in the first line.
- The second line of each test case contains $N$ space separated integers, denoting the values of array $A$.

-----Output-----
For each test case, output the maximum sum achievable in a new line.

-----Constraints-----
- $1 \le T \le 10^5$
- $1 \le N \le 10^5$
- $N$ is even
- $|A[i]| \le 10^9$
- Sum of $N$ over all test cases $\le 2 * 10^5$

-----Example Input 1-----
1
4
1 -3 2 -3

-----Example Output 1-----
9

-----Explanation 1-----
The original array is {$1, -3, 2, -3$}. Suppose you permute it and get the array {$2, 1, -3, -3$}. Then the corresponding sum would be $|2 - 1| \ + \ |-3 - (-3)| = 1 + 0 = 1$.
But suppose you permute it differently and get the array {$-3, 2, 1, -3$}. Then the corresponding sum would be $|-3 - 2| \ + \ |1 - (-3)| = 5 + 4 = 9$. You can check that you cannot do any better, and hence the answer is 9.

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}}

One day, Delta, the dog, got very angry. He has $N$ items with different values, and he decided to destroy a few of them. However, Delta loves his hooman as well. So he only destroyed those items whose Least Significant Bit in binary representation is 0. 
Can you help Delta to find the total damage he did so he could make an equally sorry face?

-----Input:-----
- First line will contain $T$, number of testcases. Then the testcases follow. 
- First line of Each test case a single integer $N$.
- Next line contains $N$ integers denoting values of items.

-----Output:-----
For each testcase, output in a single line the total damage caused by Delta.

-----Constraints-----
- $1 \leq T \leq 10^3$
- $1 \leq N \leq 10^3$
- $1 \leq value \leq 10^3$

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

$Harshad$ $Mehta$ is planning  a new scam with the stocks he is given a stock of  integer price S and a number K . $harshad$ has got the power to change the number $S$ at most $K$ times
In order to raise the price of stock and now cash it for his benefits
Find the largest price at which $harshad$ can sell the stock in order to maximize his profit 

-----Input:-----
- First line will contain $S$ and  $K$ , the price of the stock and the number K 

-----Output:-----
Print the largest profit  he can make in a single line.

-----Constraints-----
- S can take value upto 10^18
NOTE: use 64 int number to fit range
- K can take value from [0.. 9]

-----Sample Input:-----
4483 2

-----Sample Output:-----
9983

-----EXPLANATION:-----
First two digits of the number are changed to get the required number.

Given a complete binary tree with the height of H, we index the nodes respectively top-down and left-right from 1. The i-th node stores a positive integer Vi. Define Pi as follows: Pi=Vi if the i-th node is a leaf, otherwise Pi=max(Vi*PL, Vi*PR), where L and R are the indices of the left and right children of i, respectively. Your task is to caculate the value of P1.

-----Input-----
There are several test cases (fifteen at most), each formed as follows:

- The first line contains a positive integer H (H ≤ 15).
- The second line contains 2H-1 positive integers (each having a value of 109 at most), the i-th integer shows the value of Vi.
The input is ended with H = 0.

-----Output-----
For each test case, output on a line an integer which is the respective value of P1 found, by modulo of 1,000,000,007.

-----Example-----
Input:
2
1 2 3
3
3 1 5 2 6 4 7
0

Output:
3
105

Explanation:

The second test case is constructed as follows:

Chef loves to play with arrays by himself. Today, he has an array A consisting of N distinct integers. He wants to perform the following operation on his array A.

- Select a pair of adjacent integers and remove the larger one of these two. This decreases the array size by 1. Cost of this operation will be equal to the smaller of them.

Find out minimum sum of costs of operations needed to convert the array into a single element.

-----Input-----
First line of input contains a single integer T denoting the number of test cases. First line of each test case starts with an integer N denoting the size of the array A. Next line of input contains N space separated integers, where the ith integer denotes the value Ai.

-----Output-----
For each test case, print the minimum cost required for the transformation.

-----Constraints-----
- 1 ≤ T ≤ 10 
- 2 ≤ N ≤ 50000 
- 1 ≤ Ai ≤ 105 

-----Subtasks-----
- Subtask 1 : 2 ≤ N ≤ 15 : 35 pts 
- Subtask 2 : 2 ≤ N ≤ 100 : 25 pts 
- Subtask 3 : 2 ≤ N ≤ 50000 : 40 pts 

-----Example-----
Input
2
2
3 4
3
4 2 5

Output
3
4

-----Explanation-----Test 1 :  Chef will make only 1 move: pick up both the elements (that is, 3 and 4), remove the larger one (4), incurring a cost equal to the smaller one (3).

We say that two integers x and y have a variation of at least K, if |x − y| ≥ K (the absolute value of their difference is at least K). Given a sequence of N integers a1,a2,...,aN and K, the total variation count is the number of pairs of elements in the sequence with variation at least K, i.e. it is the size of the set of pairs

{(i,j)|1≤i<j≤N and|ai−aj|≥K} 

For example if K = 1 and the sequence is 3,2,4 the answer is 3. If K = 1 and the sequence is 3, 1, 3 then the answer is 2.

Your task is to write a program that takes a sequence and the value K as input and computes the total variation count.

-----Input format-----
The first line contains two positive integers N and K, separated by a space.

This is followed by a line containing N integers separated by space giving the values
of the sequence.

-----Output format-----
A single integer in a single line giving the total variation count.

-----Test data-----
You may assume that all integers in the input are in the range 0 to 10^8 inclusive.

Subtask 1 (40 marks) : 1 ≤ N ≤ 4000, 1 ≤ K ≤ 10^8 
Subtask 2 (60 marks) : 1 ≤ N ≤ 65000, 1 ≤ K ≤ 10^8 

-----Sample Input-----
3 1 
3 1 3

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