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]. 解题思路: JAVA实现如下: 1 2 3 4 5 6 7 8 9 10 11 publicvoidrotate(int[] nums,intk) { k%=nums.length; k=nums.length-k; ...
Java [Leetcode 189]Rotate Array 题目描述: 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 different ways...
} 最后贴一下最快的code(98%): public void rotate(int[] nums, int k) { int n = nums.length; k = k%n; int[] temp = Arrays.copyOfRange(nums, 0, n-k); System.arraycopy(nums, n-k, nums, 0, k); System.arraycopy(temp, 0, nums, k, n-k); } Reference:0ms 5-line java...

The standard approach to solving this problem is to first take input in the code itself. The input for our given problem is an integer number. To find log in java, to make things simpler, the Math package in Java already has a built in method named log for this. ...
