Solution: Merge Strings Alternately

Explore how to merge two strings by alternately combining their characters using the two pointers technique. This lesson helps you understand efficient string traversal, manage edge cases when string lengths differ, and analyze the time and space complexity of your solution.

We'll cover the following...

Statement

Given two strings word1 and word2, merge them by interleaving their characters in alternating order, beginning with the first character of word1. If one string is longer than the other, append the remaining characters of the longer string to the end of the merged result.

Return the resulting merged string.

Constraints:

  • 1≤1 \leq word1.length, word2.length ≤100\leq 100

  • word1 and word2 consist of lowercase English letters. ...
