It will reverse the backing array items as well. Note that the reverse() method reverses the order of the items in the original array. So if you want to keep the original array unchanged, consider cloning the array first. Reverse an Array of ObjectsString[] array = {"A", "B", "C"...
A lot simler in .NET it is: static string ReverseWords(string str) { string[] words = str.Split(' '); Array.Reverse(words); return string.Join(" ", words); } Abhinaba Basu [MSFT] August 2, 2007 Nope the .NET solution won't work as that is not constant space. E.g. your ...
01 分析 功能:字符串s倒置(倒序) 方法:递归 分析: 若将字符串"hello",实现倒置;先将每一位放到倒数第一位,然后,将第一位放到倒数二,依次交换,直到倒数位和第一位为同一位结束; 如下: var str = "hello"; //olleh elloh 第一位,放到倒数第一 交换4 ...
Use reduce() function in JavaScript to make a reverse string from an array by concatenating the string in the forward direction. // Function to reverse the string function ReverseString(str) { // Returning reverse string return [...str].reduce((x, y) =>y.concat(x)); } console.log(Re...
JavaScript does not have a built-in method for reversing a string. To reverse a string in JavaScript, you can use a combination of three built-in methods: split(), reverse(), and join(). The first method splits a string into an array of characters and returns a new array. The second...
