Solution: Check if One String Swap Can Make Strings Equal
Explore how to identify if two equal-length strings can be made equal by performing zero or one character swap on one string. Learn to track positions where strings differ and apply a verification check for swapping, enabling you to solve this problem efficiently with linear time complexity and constant space.
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.
