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,这样可以保...
intnextGreaterElement(intn) { string s = to_string(n); if(s.length() == 1) { return-1; } /* find the first decreasing digit from the right, eg: 59876, 5 is the first decreasing digit */ inti = s.length() - 2;// 21 -> i = 0; 59876 -> i = 3 for(; i >= 0 &&...

如果每一位digit依次递减, 比如"54321"就没有next greater element. return -1. 所以说节点在于不是递减的位置, "52431", 找到 “2” 和“4”的位置不是递减. 然后在2的后面比2大的最小digit, 这里是3. "2", "3"换位, 变成"53421", 再把3后面的部分sort成从小到大 "53124"就是next greater elemen...
Can you solve this real interview question? Next Greater Element I - The next greater element of some element x in an array is the first greater element that is to the right of x in the same array. You are given two distinct 0-indexed integer arrays num
public int[] nextGreaterElement(int[] findNums, int[] nums) { Map<Integer, Integer> map = new HashMap<>(); // map from x to next greater element of x Stack<Integer> stack = new Stack<>(); for (int num : nums) { //pay attention, we use nums2 to constuact our map, and ...
LeetCode 496. Next Greater Element I You are given two arrays (without duplicates) nums1 and nums2 where nums1’s elements are subset of nums2. Find all the next greater numbers for nums1's elements in the corresponding places of nums2. The Next Greater Number of a number x in nums1...
Can you solve this real interview question? Next Greater Element II - Given a circular integer array nums (i.e., the next element of nums[nums.length - 1] is nums[0]), return the next greater number for every element in nums. The next greater number of
