Leetcode 344:Reverse String 反转字符串 公众号:爱写bug Write a function that reverses a string. The input string is given as an array of characterschar[]. Do not allocate extra space for another array, you must do this bymodifying the input array in-placewith O(1) extra memory. You may...

Another way is by looping through the characters in the string you want to reverse by using the charAt() function to reposition them one by one. Sample code: publicstaticString reverseStringUsingCharAtSample(String sampleStr) {intlen = sampleStr.length(); ...

publicstaticStringreverse(finalStringarg){if(arg.length()==0){returnarg;}else{returnreverse(arg.substring(1))+arg.substring(0,1);}} 我们可以使用递归来解决类似的问题,虽然它的性能实在不敢恭维,但它确实完全符合函数式编程风格。此时,不免有一个疑问:函数式编程限制如此的多,性能看起来也不太好,我们为...
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...
