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...
[LeetCode] 189. Rotate Array 旋转数组 Given an array, rotate the array to the right byksteps, wherekis non-negative. Example 1: [1,2,3,4,5,6,7] [5,6,7,1,2,3,4] [7,1,2,3,4,5,6] [6,7,1,2,3,4,5] [5,6,7,1,2,3,4] Example 2: Input:[-1,-100,3,99]andk=...
swapArray(nums,0,numsLen-1);//反转整个数组swapArray(nums,0,k-1);//反转0到k-1索引,前k位的数组swapArray(nums,k,numsLen-1);//反转k到末尾索引,后剩余位数位的数组}privatevoidswapArray(int[] nums,intstart,intend){//反转函数inttemp;for(inti=start,j=end;i<j;i++,j--){ temp=nums[i...

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 [LeetCode]189.Rotate Array 题目 Ro...
LeetCode - 189. Rotate Array 解法一 move to a new array 移动后的index可以用 (i+k)%len [i: current index; k: 移动的位数; len: size of the array]来计算出。 解法二 no extra array 基本思想是用一个variable来记录上一个被覆盖的值 解法三 reverse trick:reverse前半段,reverse后半段,rev...
