Spiral Matrix Problem Statement

You are given a N x M matrix of integers. Your task is to return the spiral path of the matrix elements.

Input

The first line contains an integer 'T' which denotes the number of test cases or queries to be run. Then the test cases follow.

The first line of each test case contains two single space separated integers N and M, denoting the number of rows and columns respectively.

The next 'N' lines, each containing 'M' single space-separated integers representing the elements in a row of the matrix.

Output

For each test case/query, print the spiral path of the given matrix.

Output for every test case will be printed in a separate line.

Example:

Example Of Spiral Path:

Constraints:

• 1 ≤ T ≤ 5
• 1 ≤ N ≤ 10²
• 1 ≤ M ≤ 10²
• -10⁹ ≤ mat[i][j] ≤ 10⁹
• Time Limit: 1 second

Note:

You are not required to print anything; it has already been taken care of. Just implement the given function.
