There are exactly ten ways of selecting three from five, 12345: 123, 124, 125, 134, 135, 145, 234, 235, 245, and 345 In combinatorics, we use the notation, 5C3 = 10. In general, It is not until n = 23, that a value exceeds one-million: 23C10 = 114406…
这是悦乐书的第154次更新,第156篇原创 01 看题和准备 今天介绍的是LeetCode算法题中Easy级别的第13题(顺位题号是53).给定一个整数数组nums,找出一个最大和,此和是由数组中索引连续的元素组成,至少包含一个元素.例如: 输入:[-2, 1, -3, 4, -1, 2, 1, -5,4] 输出:6 说明:[4,-1,2,1]具有最大的和为6 输入:[1, 2, 3] 输出:6 说明:[1, 2, 3]具有最大的和为6 本次解题使用的开发工具是eclipse,jdk使用的版本是…
Given a set of distinct integers, S, return all possible subsets. Note: Elements in a subset must be in non-descending order. The solution set must not contain duplicate subsets. 题目要求 : 求整数数组的所有子集 注意: 1.子集元素按非降序排列 2.不包含重复的子集 解题思路: 求解这类诸如子集的题目,都可以采用回溯…
Given two words word1 and word2, find the minimum number of steps required to convert word1 to word2. (each operation is counted as 1 step.) You have the following 3 operations permitted on a word: a) Insert a characterb) Delete a characterc) Replace…

题目: Find the contiguous subarray within an array (containing at least one number) which has the largest sum. For example, given the array [-2,1,-3,4,-1,2,1,-5,4],the contiguous subarray [4,-1,2,1] has the largest sum = 6. 题解: 遍历所有组合,更新最大和. Solution 1…
Find the contiguous subarray within an array (containing at least one number) which has the largest sum. For example, given the array [−2,1,−3,4,−1,2,1,−5,4],the contiguous subarray [4,−1,2,1] has the largest sum = 6. 典型的DP问题,递推条件还是想了有点长时间,代码如下所示: cl…
