Leetcode: Rotate Array 题目: 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]. Note: Try to come up as many solutions as you can, there are at least 3 different ...
题目: Rotate an array ofn elements to the right byk steps. 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]. 将n个元素的数组按k级旋转。例如,n = 7和k = 3,数组[1,2,3,4,5,6,7]被旋转 dynamic-programming-python-leetcode(动...
Can you solve this real interview question? Rotate Array - Given an integer array nums, rotate the array to the right by k steps, where k is non-negative. Example 1: Input: nums = [1,2,3,4,5,6,7], k = 3 Output: [5,6,7,1,2,3,4] Explanation: rotate 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]. 双数组 复杂度 时间O(N) 空间 O(N) 思路 建立一个新数组,将位移过的数字放在新的数组中。
LeetCode之“数组”:Rotate Array 题目链接 题目要求: 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]. Note: Try to come up as many solutions as you can, there are at least 3 ...
LeetCode 189: Rotate Array (Java) 题目: 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]. 两种解法: 第一种是原地swap,记录下被挤掉的数再接着swap,需要一些时间举栗子...
LeetCode笔记:189. Rotate Array 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 [5,6,7,1,2,3,4]。 思路: 旋转本身没太多特别好说的,我的做法是用另一个数组来记录旋转后的内容,然后复制回原数组。当然记录时是从第nums.length-k个元素...
