Grokking the Coding Interview Patterns

Find the Difference

Explore how to identify the first occurrence of an extra character between two similar strings by applying bitwise manipulation techniques. This lesson helps you understand constraints and implement an efficient solution where string lengths differ by one, enhancing your problem-solving skills for coding interviews.

We'll cover the following...

Statement

Given two strings, str1 and str2, find the index of the extra character that is present in only one of the strings.

Note: If multiple instances of the extra character exist, return the index of the first occurrence of the character in the longer string.

Constraints:

  • 0≤0
