Mar 20, 2023 · Given two strings S1 and S2, the task is to check whether they are the same or not without using string library functions. Examples: Approach: Follow the steps below to solve the problem: If the lengths of S1 and S2 are different, return false. If S1 [i] is not equal to S2 [i], return false. Return true at the end of the traversal.
