Example: There is a string array that first sorts each string in the array alphabetically, and then sorts the entire string in dictionary order. Time complexity of the entire operation?A: Suppose the longest string length is s, and there are n strings in the array.Sort each string: slogs, total N, so nslog (s)Sort all strings: O (S*nlog (n))//Sort the string, with a maximum of s per comparison==> O (n * slogs) + O (S * nlogn) = O (sn(Logn + logs))Algorithmic complexity in some cases is related t
