直接返回一个新的vector,初始化的内容就是数组a从右到左的值。 vector<int> reverseArray(vector<int> a) { return {a.rbegin(), a.rend()}; } 方法四: 这个是使用C++STL库里的reverse函数,需要包含<algorithm>头文件。 vector<int> reverseArray(vector<int> a) { reverse(a.begin(),a.end()); r...
// sizeof(my_array) 获取整个数组占用的总字节数 // sizeof(my_array[0]) 获取数组单个元素占用的字节数 size_t num_elements = sizeof(my_array) / sizeof(my_array[0]); printf("原始数组 (共 %zu 个元素): ", num_elements); for (size_t i = 0; i < num_elements; i++) { printf(...
How to Reverse an Array in C# Syed Hassan Sabeeh KazmiFeb 02, 2024 CsharpCsharp Array This tutorial will teach you different ways to reverse an array in C#, including predefined methods. Generally it requires the creation of atempvariable to store the first index value of an arraytemp = ...
The article showcase an array to be reversed in descending order using the C++ coding wherein the highest index is swapped to lowest index consequently by traversing the array in the loop. Example Live Demo #include <iostream> #include <algorithm> using namespace std; void reverseArray(int ...
Program to reverse copy array in CPrevious Quiz Next This program shall help you learn one of basics of arrays. We shall copy one array into another but in reverse.AlgorithmLet's first see what should be the step-by-step procedure of this program −...
Alternatively, to reverse the array elements in place without declaring other variables, we can call thestd::reversefunction from the standard library.std::reverseis part of the<algorithm>header and has been part of the standard library since the C++17. The function takesstart/enditerators of th...
reverse(array) 其中,array是要反转的数组。该函数会返回一个新数组,其中包含了原数组中的元素顺序反转后的结果。如果原数组为空或不存在,则返回原数组。 例如,在JavaScript中,可以使用reverse函数来反转一个数组: vararr=[1,2,3,4,5]; varreversedArr=arr.reverse(); console.log(reversedArr);//输出[5,4...
reverse(); // ['c', 'b', 'a']; # Examples# Array of Numbersconst nums = [2, 10, 5]; nums.reverse; // [5, 10, 2] # Array of EmojisNope, "emojis" aren't a type. It's just a string. Notice the quotation around it. It's important to have fun in programming, I ...
The same swapping goes on in the for-loop until we hit the middle of the array, at this time the array has been reversed. String[] array = {"A", "B", "C", "D", "E"}; for (int i = 0; i < array.length / 2; i++) { String temp = array[i]; array[i] = array[arr...
JavaScript(JS) array.reverse() Array对象允许在一个变量中存储多个值。它存储相同类型元素的固定大小的顺序集合。数组用于存储数据集合,但将数组看作同一类型变量的集合通常更有用。本文主要介绍JavaScript(JS) array.reverse() 方法。 1、描述 方法用于reverse()数组中的元素。数组的第一个元素变成最后一个元素,...
