Increase Elements by N

You are given T test cases. For each test case, you are provided with an integer N and a list of integers.

Your task is to increase each element in the list by N and print the updated list.

The operation for a test case can be mathematically represented as:

\(a_i^{\prime} = a_i + N\) for each element \(a_i\) in the list.

Note that N can be positive, negative, or zero.

inputFormat

The first line contains an integer T indicating the number of test cases.

For each test case, the input consists of two lines:

• The first line contains two integers N and M, where N is the value to add and M is the number of elements in the list.
• The second line contains M space-separated integers.

All input should be read from standard input (stdin).

outputFormat

For each test case, output a single line containing the updated list of integers after each element has been increased by N. The numbers should be separated by a single space.

All output should be written to standard output (stdout).
