C) Declare a temporary array to store the available colors.
WebGreedy algorithms are an approach to solution determined kinds von optimization problems. Greedy algorithms are similar to dynamic programming algorithms in this the solutions are both efficient and optimised if which problem exhibits some particular sort of substructure.
