使用两层循环,先找到nums1的元素在nums2中的对应元素,然后从nums2中找到的元素的下一位往右开始判断,找到比当前元素大的元素,找得到就将其作为结果数组的元素添加进去,否则就将-1添加进结果数组。 publicint[]nextGreaterElement(int[] nums1,int[] nums2){int[] result =newint[nums1.length];for(inti=0;...
Given a positive32-bitintegern, you need to find the smallest32-bitinteger which has exactly the same digits existing in the integernand is greater in value than n. If no such positive32-bitinteger exists, you need to return -1. Example 1: Input:12 Output:21 Example 2: Input:21 Outpu...

Leetcode 556. Next Greater Element III 2. Solution **解析:**Version 1,先将数字n变为字符数组,要找最小的大于n的数,则应该从右往左开始,依次寻找第i位字符右边的大于当前字符的最小数字,然后互换二者位置,由于新数字的第i位字符大于n中的第i位字符,因此新数字i位之后的字符应该从小到大排列,这样可以...
