Solution: Merge Strings Alternately
Understand how to merge two strings by interleaving their characters using the two pointers technique. This lesson helps you implement a method that traverses both strings simultaneously, appends characters alternately, and handles remaining characters efficiently. Mastering this approach enhances your problem-solving skills for string handling in 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. ...
