How to check if two strings have a common substring?

A basic approach runs in O (n^2), where we compare every character of string 1 with every character of string 2 and replace every matched character with a “_” and set flag variable as true. An efficient approach works in O (n). We basically need to check if there is a common character or not.

How to print common characters of two strings?

Input : string1 : geeks string2 : forgeeks Output : eegks Explanation: The letters that are common between the two strings are e (2 times), k (1 time) and s (1 time). Hence the lexicographical output is “eegks” Input : string1 : hhhhhello string2 : gfghhmh Output : hhh
