publicStringreverseString(Strings) {StringBuildersb =newStringBuilder(s);returnsb.reverse().toString(); } 03 第二种解法 使用双指针,一个从0开始,一个从字符串尾部开始,利用循环,进行首尾字符互换。 publicStringreverseString2(String s){if(s ==null|| s.trim().length() <=1) {returns; }inti =0...
Write a function that takes a string as input and reverse only the vowels of a string. Example 1: Givens = "hello", return "holle". Example 2: Givens = "leetcode", return "leotcede". Note 第一种解法:将字符串转化为字符数组,用一头一尾两个指针向中间夹逼,遇到两个元音字母就进行位置交换...
bool checkDifferent(string iniString) { // write code here bool hashchar[128]; memset(hashchar,0,sizeof(hashchar)); for(char a:iniString){ if(hashchar[a])//如果出现过返回 return false; else hashchar[a]=true;//没出现过的字符登记 ...
