Solution: Merge Strings Alternately

Explore the technique of merging two strings alternately by using two pointers that traverse both strings simultaneously. This lesson guides you through implementing a solution that efficiently combines characters in alternating order and handles strings of unequal lengths, while understanding the time and space complexity involved.

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. ...
