Alien Dictionary problem: Sorted order of characters
In this article, we are given a sorted list of words in some alien dictionary. Based on the list, we have to generate the sorted order of characters in that alphabet. This problem can be solved using the idea of Topological Sort and Direct Acyclic Graphs.
Longest Common Suffix Problem
In this article, we will see how we can find the longest common suffix (i.e ending) that all the strings given to us have. We shall start with the brute-force approach for two strings. Following this, we will implement the Trie data structure to solve the problem for more than two strings.
