WebGreedy algorithms build a solution part by part, choosing the next part in such a way, that it gives an immediate benefit. This approach never reconsiders the choices taken previously. This approach is mainly used to solve optimization problems. Greedy method is easy to implement and quite efficient in most of the cases. WebMerging is the process of combing two sorted array to form a single large array, this is more precisely called Two-way merge. Merge has a time complexity of \(\theta(n + m)\). The …
