Solution: Check if One String Swap Can Make Strings Equal
Understand how to check if two strings of the same length can be made equal by performing at most one swap operation in one string. Learn to identify differing character positions and verify if swapping them will equalize the strings, with an emphasis on time and space efficiency.
We'll cover the following...
Statement
You are given two strings s1 and s2 of equal length. A string swap operation allows you to choose two indices in a string (not necessarily different) and swap the characters at those indices.
Determine whether it is possible to make the two strings equal by performing at most one string swap on exactly one of the strings. Return TRUE if this is possible, and FALSE otherwise.
Note: The swap is performed on exactly one of the two strings, and you may choose to perform zero or one swap.
