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 ...
return a; } 方法二: 思路是:新建一个数组b,从后往前遍历数组a,把遍历到的元素加到数组b的后面。 时间复杂度是O(n),需要遍历n次。 空间复杂度是O(n),因为要开辟与输入的数组一样大的空间。 vector<int> reverseArray(vector<int> a) { vector<int> b; for(vector<int>::iterator x = a.end()-...
// 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...
procedure reversecopy_array(A, B) SET index to 1 Set count to sizeof(A) FOR EACH value in A DO B[count] = A[index] INCREMENT index DECREMENT count END FOR DISPLAY B end procedure ImplementationThe implementation of the above derived pseudocode is as follows −...
String[] array = {"A", "B", "C", "D", "E"}; ArrayUtils.reverse(arr); System.out.println(Arrays.toString(arr)); //[E, D, C, B, A] 5. Conclusion In this short tutorial, we learned to reverse an array using different techniques. We learned to use for-loop, swapping items,...

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...
Use the reverse() function in JavaScript to reverse the array of characters i.e.[ ‘n’, ‘m’, ‘a’, ‘d’, ‘e’, ‘d’, ‘o’, ‘c’, ]. Use the join() function in JavaScript to concatenate the elements of an array into a string. // <em>Function to reverse string</...
