Given an array, rotate the array to the right by k steps, where k is non-negative. Example 1: Input: [1,2,3,4,5,6,7] and k = 3 Output: [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 the right: [6,7,1,2,3,4…

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 ways to solve this pro…

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]. 解题思路: JAVA实现如下: public void rotate(int[] nums, int k) { k%=nums.length; k=nums.length-k; int[] nums2=ne…

题意:将数组旋转k次,如将数组[1,2,3,4,5]旋转1次得到[2,3,4,5,1],将数组[1,2,3,4,5]旋转2次得到[3,4,5,1,2]..... 本质是将数组分成两部分a1,a2,...ak以及ak+1....an两部分,然后将两部分进行交换. 我的解法是将数组分成两部分a1,a2,.....an-k-1以及an-k,.....an,然后将两部分分别反转得到数组ank-1,.....,a2,a1,an......an-k 然后将这个数组反转得到an-k,.....an,a1,a2…
