Determine if a given graph is Bipartite Graph using DFS

Given a graph, determine if given graph is bipartite graph using DFS. A bipartite graph (or bigraph) is a graph whose vertices can be divided into two disjoint sets U and V such that every edge connects a vertex in U to one in V.

Flood Fill Algorithm

Flood fill (also known as seed fill) is an algorithm that determines the area connected to a given node in a multi-dimensional array.

Find all occurrences of given string in a character matrix

Given a M x N matrix of characters, find all occurrences of a given string in the matrix. We are allowed to search the string in all eight possible directions i.e. North, West, South, East, North-East, North-West, South-East, South-West. Note that there should not be any cycles in the output path.
