Next Permutation leetcode java 题目: Implement next permutation, which rearranges numbers into the lexicographically next greater permutation of numbers. If such arrangement is not possible, it must rearrange it as the lowest possible order (ie, sorted in ascending order). The replacement must be i...

1.2 next_permutation原理 第一次接触到next_permutation的原理,是在侯捷老师的《STL源码解析》的书里,这本书看完我大受裨益,非常可惜Java没有这种深入浅出的入门级源码解析著作。 next_permutation的实现思路很巧妙: 对于一个序列,从尾端开始往前遍历每一对相邻的两个元素 *i 和 *ii,找到第一对满足 *i < *...
