Solution: Merge Strings Alternately
Explore how to merge two strings by alternating their characters using the two-pointer technique. Understand how to traverse both strings simultaneously and handle remaining characters to create a merged result. This lesson helps you implement a linear time solution for combining strings in Python, enhancing your problem-solving skills for coding interviews.
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:
word1.length,word2.lengthword1andword2consist of lowercase English letters. ...
