For the remaining matrix, if mat[i][j] is 0 then set mat[i][0] and mat[0][j] to 0. Set Matrix Zeros: Given a matrix, A of size M x N of 0s and 1s. If an element is 0, set its entire row and column to 0. Note: This will be evaluated on the extra memory used. Try to minimize the space and time complexity. If any cell of the matrix has a zero we can record its row and column number using additional memory. But if you don't want to use extra memory then you can manipulate the array instead. i.e. simulating exactly what the question says. Sep 26, 2020 · If any item in the matrix is zero then set its complete row and its complete column zero. Solution. Process the first row and first column separately.

Do you have a big interview coming up with Google or Facebook? Matrix Search: Given a matrix of integers A of size N x M and an integer B. Write an efficient algorithm that searches for integar B in matrix A. This matrix A has the following properties: * Integers in each row are sorted from left to right. * The first integer of each row is greater than or equal to the last integer of the previous row. Return 1 if B is present in A, else return 0. Note ... traverse the matrix if matrix[i][j] = 0 than set the corresponding bits in the row and col; after traversal traverse again and set the matrix[i][j] = 0 if corresponding bit of either row or column is set. The time complexity is same O(N^2) but it is memory efficient. Please find my code below . In the following solution, sumRemaining tracks the sum of remaining to the current index. If sumRemaining 0, then every index between old start and current index is bad, and we need to update start to be the current index. You can use the following example to visualize the solution.
