You are given two strings word1 and word2. You want to construct a string merge in the following way: while either word1 or word2 are non-empty, choose one of the following options:

\n\n\n\n

Return the lexicographically largest merge you can construct.

\n\n

A string a is lexicographically larger than a string b (of the same length) if in the first position where a and b differ, a has a character strictly larger than the corresponding character in b. For example, "abcd" is lexicographically larger than "abcc" because the first position they differ is at the fourth character, and d is greater than c.

\n\n

 

\n

Example 1:

\n\n
\nInput: word1 = "cabaa", word2 = "bcaaa"\nOutput: "cbcabaaaaa"\nExplanation: One way to get the lexicographically largest merge is:\n- Take from word1: merge = "c", word1 = "abaa", word2 = "bcaaa"\n- Take from word2: merge = "cb", word1 = "abaa", word2 = "caaa"\n- Take from word2: merge = "cbc", word1 = "abaa", word2 = "aaa"\n- Take from word1: merge = "cbca", word1 = "baa", word2 = "aaa"\n- Take from word1: merge = "cbcab", word1 = "aa", word2 = "aaa"\n- Append the remaining 5 a's from word1 and word2 at the end of merge.\n
\n\n

Example 2:

\n\n
\nInput: word1 = "abcabc", word2 = "abdcaba"\nOutput: "abdcabcabcaba"\n
