DSA problem
Merge Strings Alternately
You are given two strings word1 and word2. Merge the strings by adding letters in alternating order, starting with word1.
If a string is longer than the other, append the additional letters onto the end of the merged string.
Return the merged string.
Examples
Example 1
Input:
word1 = "abc", word2 = "pqr"Output:
"apbqcr"Explanation: The merged string interleaves the characters: a p b q c r.
Example 2
Input:
word1 = "ab", word2 = "pqrs"Output:
"apbqrs"Explanation: As word2 is longer, "rs" is appended to the end.
Example 3
Input:
word1 = "abcd", word2 = "pq"Output:
"apbqcd"Explanation: As word1 is longer, "cd" is appended to the end.
Constraints
- 1 <= word1.length, word2.length <= 100
- word1 and word2 consist of lowercase English letters.
