Consider a directed graph where weight of its edges can be one of x, 2x or 3x (x is a given integer), compute the least cost path from source to destination efficiently.
Given a N x N matrix of positive integers, find shortest path from the first cell of the matrix to its last cell that satisfies given constraints.
Given a binary matrix where 0 represents water and 1 represents land, count the number of islands in it. A island is formed by connected one’s. For example, consider below image. Above image highlights water in blue and land in grey in a 10 x 10 matrix. There are total five islands present in the above …
Flood fill (also known as seed fill) is an algorithm that determines the area connected to a given node in a multi-dimensional array.
Given a rectangular field with few sensors present on it, cross it by taking the shortest safe route without activating the sensors. The rectangular field is given in the form of M x N matrix and we need to find the shortest path from any cell in first column to any cell in the …
