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; ...
} 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...
