Enter both have small to large order, good strings to write a function merge two strings, so the string after the merger, is still ascending order. Input: two have been in good order (ascending) two string output: a combined ordered (ascending) string requirements: design an efficient algorithm is as high as possible, scan only once for each string on it. If you were using the first serial connection, and then sort of algorithm, the efficiency is too low.
