Given two Strings, str1 and str2, each is already arranged in lexicographic order, combine them in lexicographic order and return the result as a String. Assume all strings are composed of only lowercase letters.

strCombine("abc", "def") → "abcdef"
strCombine("ad", "be") → "abde"
strCombine("ad", "bde") → "abdde"

...Save, Compile, Run (ctrl-enter)

public String strCombine(String str1, String str2) { }
