Solution 3. O(n) runtime, O(1) space, using reverse algorithm 1. decide on the split point depending if it is a left or right rotation. 2. reverse the splitted array separately, then reverse the whole array. 1privatevoidreverse(int[] arr,intstart,intend) {2while(start <end) {3arr...
Rotate an Array Rotate an Array 90 degrees clockwise without extra space. e.g: [[1,2,3],[4,5,6],[7,8,9]] -> [[7,4,1],[8,5,2],[9,6,3]] Solution: we can take an example of 5*5 matrix and take two points to see the transformation("->"means reaches) (0,1)->(1...
Rotate an array of n elements to the right by k steps. For example, with n = 7 and k = 3, the array [1,2,3,4,5,6,7] is rotated to [5,6,7,1,2,3,4]. 大意: 旋转一个有n个元素的数组,右移k步。 比如,n = 7,k = 3,数组 [1,2,3,4,5,6,7] 就被旋转为 [5,6,7...
189. Rotate Array 从右边开始翻转数组 [抄题]: Rotate an array ofnelements to the right byksteps. For example, withn= 7 andk= 3, the array[1,2,3,4,5,6,7]is rotated to[5,6,7,1,2,3,4]. [暴力解法]: 时间分析: 空间分析: [优化后]: 时间分析: 空间分析: [奇葩输出条件]: [奇...

Let’s say, we are required to write a JavaScript function that takes in an array and a number n and rotates the array by n elements For example: If the input array is − const arr = [12, 6, 43, 5, 7, 2, 5]; and number n is 3, Then the output should be − const ...
Rotate Array 描述 Rotate an array ofnelements to the right byksteps. For example, withn = 7andk = 3, the array[1,2,3,4,5,6,7]is rotated to[5,6,7,1,2,3,4]. Note: Try to come up as many solutions as you can, there are at least 3 different ways to solve this problem....
Array - 189. Rotate Array 189、Rotate Array Given an array, rotate the array to the right byksteps, wherekis non-negative. Example 1: Input:[1,2,3,4,5,6,7] andk= 3Output:[5,6,7,1,2,3,4]Explanation:rotate 1 steps to the right: [7,1,2,3,4,5,6] rotate 2 steps to ...
Given the arraynumsafterthe possible rotation and an integertarget, returnthe index oftargetif it is innums, or-1if it is not innums. You must write an algorithm withO(log n)runtime complexity. Example 1: Input:nums = [4,5,6,7,0,1,2], target = 0Output:4 ...
