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...

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...
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 ...
If we want to make a function to reverse a given array, we can use aforloop and thelengthfunction in JavaScript. Thelengthfunction returns the number of elements of a given array. To make our function work, we have to get each element of the given array from the end, store it at th...
The second call uses the preserve_keys argument. And the third call shows that non-numeric keys are preserved automatically, even if the preserve_keys argument is not given.us code Code Output Hide output 1 2 3 4 5 6 7 8 <?php $a = array(0=>"coffee",1=>"toast",2=>"jam");...
The length of the given array will not exceed50,000. All the numbers in the input array are in the range of 32-bit integer. 这道题第一次做的时候就感觉和Count of Smaller Numbers After Self很像,开始也是用的二分查找法来建立有序数组,LintCode 上也有一道非常类似的题Reverse Pairs 翻转对,虽然...
asList(array)); //Does not reverses the array 2. Swapping Array Elements in For Loop Another simple and straightforward way is to iterate through the array swapping them from the beginning position with the elements in the last position. For example, the given image describes the swapping ...
