Function: countOddEven
Purpose: Counts how many odd and even numbers exist in the matrix.
Parameters:
- matrix: the 2D sequence
- rows: number of rows in the matrix (computed inside the function)
- cols: number of columns in the matrix (computed inside the function)
- odd: variable to store odd count
- even: variable to store even count
