leetcode -- Next Permutation -- 重点常考 https://leetcode.com/problems/next-permutation/ 参考:http://fisherlei.blogspot.hk/2012/12/leetcode-next-permutation.html 算法巧妙。记住那个算法流程图 思路: 总体来说就是从后往前找到第一个递减的数,然后在这个数的右半部分中找到一个比这个数大的最小值,...
31. Next Permutation Medium CompaniesA permutation of an array of integers is an arrangement of its members into a sequence or linear order. For example, for arr = [1,2,3], the following are all the permutations of arr: [1,2,3], [1,3,2], [2, 1, 3], [2, 3, 1], [3,...
31. Next Permutation 题目描述(中等难度) 这道题的的难度我觉得理解题意就占了一半。题目的意思是给定一个数,然后将这些数字的位置重新排列,得到一个刚好比原数字大的一种排列。如果没有比原数字大的,就升序输出。 关键就是刚好是什么意思?比如说原数字是 A,然后将原数字的每位重新排列产生了 B C D E,...
