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...
// 交换 my_array[left] 和 my_array[right] 的值 int temp = my_array[left]; // 1. 将左边的值存入临时变量 my_array[left] = my_array[right]; // 2. 将右边的值赋给左边 my_array[right] = temp; // 3. 将临时变量的值赋给右边 (完成交换) // 移动下标,向中间靠拢 left++; // 左...
Hint: Make use of macros to assign size of the array. And both the arrays must have same size. Related Read:Basics of Arrays: C Program Example: Expected Output Enter 5 integer numbers52643 Copying elements from array a to bIn reverse Order Original(a[5]) –> Copy(b[5])5–> 3...
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...

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 ...
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...

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,...
