Given an integer matrix matrix, you are tasked to return a tuple containing the row and column indices of the integer target. If the target is not in the matrix, return None.

The following are the properties of the matrix:

• Each list within the matrix has equal sizes, meaning the matrix is a square or rectangle.
• Each row is sorted in increasing order.
• The first integer of a row is larger than the last integer of the previous row.

Example 1:

Input: matrix = [[1,2,4,5], [6,8,10,12], [13,15,17,20], [21,22,24,26]], target = 10 Output: (1,2)

Example 2:

Input: matrix = [[1,2,4,5], [6,8,10,12], [13,15,17,20], [21,22,24,26]], target = 11 Output: None
