[Leet Code] Merge Strings Alternately
You are given two strings
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.
Input: word1 = "abc", word2 = "pqr"
Explanation: The merged string will be merged as so:
word1: a b c
word2: p q r
merged: a p b q c r
Input: word1 = "ab", word2 = "pqrs"
Explanation: Notice that as word2 is longer, "rs" is appended to the end.
word1: a b
word2: p q r s
merged: a p b q r s
Input: word1 = "abcd", word2 = "pq"
Explanation: Notice that as word1 is longer, "cd" is appended to the end.
word1: a b c d
word2: p q
merged: a p b q c d
1 <= word1.length, word2.length <= 100
word2consist of lowercase English letters.
