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.

\r\n\r\n

Return the merged string.

\r\n

Example 1:

\r\n\r\n
\r\nInput: word1 = "abc", word2 = "pqr"\r\nOutput: "apbqcr"\r\nExplanation: The merged string will be merged as so:\r\nword1:  a   b   c\r\nword2:    p   q   r\r\nmerged: a p b q c r\r\n
\r\n\r\n

Example 2:

\r\n\r\n
\r\nInput: word1 = "ab", word2 = "pqrs"\r\nOutput: "apbqrs"\r\nExplanation: Notice that as word2 is longer, "rs" is appended to the end.\r\nword1:  a   b \r\nword2:    p   q   r   s\r\nmerged: a p b q   r   s\r\n
\r\n\r\n

Example 3:

\r\n\r\n
\r\nInput: word1 = "abcd", word2 = "pq"\r\nOutput: "apbqcd"\r\nExplanation: Notice that as word1 is longer, "cd" is appended to the end.\r\nword1:  a   b   c   d\r\nword2:    p   q \r\nmerged: a p b q c   d\r\n

Constraints:

\r\n\r\n", "translatedTitle": "交替合并字符串", "translatedContent": "

给你两个字符串 word1word2 。请你从 word1 开始,通过交替添加字母来合并字符串。如果一个字符串比另一个字符串长,就将多出来的字母追加到合并后字符串的末尾。

\n\n

返回 合并后的字符串

\n\n

 

\n\n

示例 1:

\n\n
\n输入:word1 = \"abc\", word2 = \"pqr\"\n输出:\"apbqcr\"\n解释:字符串合并情况如下所示:\nword1:  a   b   c\nword2:    p   q   r\n合并后:  a p b q c r\n
\n\n

示例 2:

\n\n
\n输入:word1 = \"ab\", word2 = \"pqrs\"\n输出:\"apbqrs\"\n解释:注意,word2 比 word1 长,\"rs\" 需要追加到合并后字符串的末尾。\nword1:  a   b \nword2:    p   q   r   s\n合并后:  a p b q   r   s\n
\n\n

示例 3:

\n\n
\n输入:word1 = \"abcd\", word2 = \"pq\"\n输出:\"apbqcd\"\n解释:注意,word1 比 word2 长,\"cd\" 需要追加到合并后字符串的末尾。\nword1:  a   b   c   d\nword2:    p   q \n合并后:  a p b q c   d\n
