Coding made easy

Given a M x N binary matrix, fill it with alternating rectangles of 0 and 1.

Given a square matrix, print maximum length snake sequence in it. A Snake sequence is defined as a sequence of numbers where each new number, which can only be located to the right or down of the current number, is either plus or minus one.

Given a square matrix, rotate the matrix by 180 degrees in clock-wise direction. The transformation should be done in-place in quadratic time.

Given an NxN matrix, check if it is Toeplitz matrix or not. A Toeplitz matrix or diagonal-constant matrix is a matrix in which each descending diagonal from left to right is constant.

Given a M x N matrix where each cell can have value of 1, 0 or -1, where -1 denotes a unsafe cell, collect maximum number of ones starting from first cell and by visiting only safe cells (i.e. 0 or 1). We are allowed to go only left or down if the row is …

Given a M x N matrix where each cell have non-negative cost associated with it, count number of paths to reach last cell (M-1, N-1) of the matrix from its first cell (0, 0) such that path has given cost. We can only move one unit right or one unit down from any cell. i.e. …

Given a N x N matrix where each cell has distinct value in the 1 to N * N. Find the longest sequence formed by adjacent numbers in the matrix such that for each number, the number on the adjacent neighbor is +1 its value.

Given a M x N matrix where each cell has a cost associated with it, find the minimum cost to reach last cell (M-1, N-1) of the matrix from its first cell (0, 0). We can only move one unit right or one unit down from any cell. i.e. from cell (i, j), we can …

Matrix chain multiplication problem: Determine the optimal parenthesization of a product of n matrices.

Given a M x N binary matrix, find the size of largest square sub-matrix of 1’s present in it.

Given an M x M matrix, find maximum sum submatrix present in it.

Given a M x N matrix, calculate maximum sum submatrix of size k x k in a given M x N matrix in O(M*N) time. Here, 0 < k < M, N.
