Algorithm： Permutation & Combination

组合计数组合数学主要是研究一组离散对象满足一定条件的安排的存在性、构造及计数问题。计数理论是狭义组合数学中最基本的一个研究方向，主要研究的是满足一定条件的排列组合及计数问题。组合计数包含计数原理、计数方法、计数公式。组合计数基本原理加法原理\[如果一个目标的实现可以在n种不同的情况下完成，且对于第i种情况又有m_i种不同的方法，\\那么总的方法数N为：N=m_1+m_2+...+m_n=\sum_

A general approach to backtracking questions in Java (Subsets, Permutations, Combination Sum, Palindrome

在一亩三分地上看到leetcode里有样的summary，今天早上看了一下，下面是我的总结。Subsets下面的代码是很久前写的了，当时是什么都不懂。。再看这个代码，发现有个奇怪的地方就是它的递归没有显式的Terminator（终止条件），这里的for循环就相当于terminator，因为start每次都会+1。所以for循环不满足之后，dfs函数执行完了就会自动return，所有的return都

Combination Sum 目标数字的加数分解

一、概述输入一个数组和一个数字，在数组中找到所有数字组合，组合中元素之和等于输入的数字。一看就是DFS，没的说。关键是DFS如何优化。我的DFS效果不咋地：那就拿这道题来看看怎么优化吧。时间缩短了三倍。二、分析1、我的算法仅仅简单的DFS是完全不够用的。一定需要剪枝。我选择的剪枝方法是基于输入数组的有序性做的：对数组进行遍历，如果当前和加上当前的数组元素比target大，那之后的元素就不用看了。用
