1768. Merge Strings Alternately Easy

1/**
2 * [1768] Merge Strings Alternately
3 *
4 * 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.
5 * 
6 * Return the merged string.
7 * 
8 *  
9 * Example 1:
10 * 
11 * 
12 * Input: word1 = "abc", word2 = "pqr"
13 * Output: "apbqcr"
14 * Explanation: The merged string will be merged as so:
15 * word1:  a   b   c
16 * word2:    p   q   r
17 * merged: a p b q c r
18 * 
19 * 
20 * Example 2:
21 * 
22 * 
23 * Input: word1 = "ab", word2 = "pqrs"
24 * Output: "apbqrs"
25 * Explanation: Notice that as word2 is longer, "rs" is appended to the end.
26 * word1:  a   b 
27 * word2:    p   q   r   s
28 * merged: a p b q   r   s
29 * 
30 * 
31 * Example 3:
32 * 
33 * 
34 * Input: word1 = "abcd", word2 = "pq"
35 * Output: "apbqcd"
36 * Explanation: Notice that as word1 is longer, "cd" is appended to the end.
37 * word1:  a   b   c   d
38 * word2:    p   q 
39 * merged: a p b q c   d
40 * 
41 * 
42 *  
43 * Constraints:
44 * 
45 * 
46 * 	1 <= word1.length, word2.length <= 100
47 * 	word1 and word2 consist of lowercase English letters.
48 *
