Given a stringS, return the "reversed" string where all characters that are not a letter stay in the same place, and all letters reverse their positions. 题目分析及思路 给定一个字符串,返回“reversed”后的字符串,要求非字母的字符保留原来的位置,字母字符逆序排列。可以先获得原字符串中的全部字母字...
方法: 两个指针向中间移动,当左右指针相遇时停止,每个指针在遇到非字母时直接跳过,当左右指针都指向字母时交换,不断重复直到指针相遇。 classReverseOnlyLetters{funreverseOnlyLetters(S:String):String{valresult=CharArray(S.length)varstart=0varend=S.lastIndexwhile(start<=end){if(!S[start].isLetter()){re...
