What is Set Matrix Zeroes?
Given a matrix, if any cell is zero, set its entire row and column to zero, in place. The trick is to record which rows and columns need zeroing before making any changes, using the first row and column as markers to avoid extra space. This problem teaches you to use existing space within the matrix to avoid allocating extra memory, a useful in-place technique.
