    1754 - Largest Merge Of Two Strings.

    Medium

    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:

    • If word1 is non-empty, append the first character in word1 to merge and delete it from word1.
      • For example, if word1 = "abc" and merge = "dv", then after choosing this operation, word1 = "bc" and merge = "dva".
    • If word2 is non-empty, append the first character in word2 to merge and delete it from word2.
      • For example, if word2 = "abc" and merge = "", then after choosing this operation, word2 = "bc" and merge = "a".

    Return the lexicographically largest merge you can construct.

    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.

    Example 1:

    Input: word1 = “cabaa”, word2 = “bcaaa”

    Output: “cbcabaaaaa”

    Explanation: One way to get the lexicographically largest merge is:

    • Take from word1: merge = “c”, word1 = “abaa”, word2 = “bcaaa”

    • Take from word2: merge = “cb”, word1 = “abaa”, word2 = “caaa”

    • Take from word2: merge = “cbc”, word1 = “abaa”, word2 = “aaa”

    • Take from word1: merge = “cbca”, word1 = “baa”, word2 = “aaa”

    • Take from word1: merge = “cbcab”, word1 = “aa”, word2 = “aaa”

    • Append the remaining 5 a’s from word1 and word2 at the end of merge.

    Example 2:

    Input: word1 = “abcabc”, word2 = “abdcaba”

    Output: “abdcabcabcaba”

    Constraints:

    • 1 <= word1.length, word2.length <= 3000
    • word1 and word2 consist only of lowercase English letters.
