Maximum Number of Ones

Consider a matrix M with dimensions width * height, such that every cell has value 0 or 1, and any square sub-matrix of M of size sideLength * sideLength has at most maxOnes ones.

Return the maximum possible number of ones that the matrix M can have.

Example 1:

Input: width = 3, height = 3, sideLength = 2, maxOnes = 1

Output: 4

Explanation:
In a 3*3 matrix, no 2*2 sub-matrix can have more than 1 one.
The best solution that has 4 ones is:
[1,0,1]
[0,0,0]
[1,0,1]

Example 2:

Input: width = 3, height = 3, sideLength = 2, maxOnes = 2

Output: 6

Explanation:
[1,0,1]
[1,0,1]
[1,0,1]

Constraints:

• 1 <= width, height <= 100
• 1 <= sideLength <= width, height
• 0 <= maxOnes <= sideLength * sideLength
