- Description
- You will be given N integers v0,v1,v2...vN-1 and an integer M.
Can you tell me the number of distinct integer values of x such that:
|v0 - x| + |v1 - x| + ... + |vN-1 - x| ≤ M.
- Input
- The first line of the input will be a integer to represent the number of test cases.
For each case there is two lines.
The first line contains two integers N and M.
The second line contains N integers v0,v1,v2...vN-1.
( 1 <= N <= 50000 , 0 <= M <= 10^9 , -10^9 <= vi <= 10^9 )
There is a blank line before each test case. - Output
- For each test case output the answer on a line:
The number of distinct integer values of x. - sample input
