Unique Paths Problem Statement
Given the dimensions of an M x N matrix, determine the total number of unique paths from the top-left corner to the bottom-right corner of the matrix.
Allowed moves are only to the right or down at each step.
Input:
The first line contains an integer 'T', the number of test cases.
For each test case, a single line contains two space-separated integers 'M' and 'N', representing the number of rows and columns of the matrix, respectively.
Output:
For each test case, output a single integer representing the total number of unique paths from the top-left to the bottom-right cell of the matrix.
Print the output for each test case on a new line.
Example:
Input:
T = 2
M = 2, N = 2
M = 3, N = 3
Output:
2
6
Constraints:
1 ≤ T ≤ 100
1 ≤ M ≤ 15
1 ≤ N ≤ 15
- The time limit is 1 second
Note:
There is no need for you to print anything; simply implement the function to compute the results.
