Pitfall: Template for two-pointer; Be careful when calculating length. Pitfall: There are two ways of calculating length. One is by using "i" and the other is to use (nums.length - (j - i)). View Code 12.Subarray Sum -Not Bug Free -Not Bug Free 坑:edge cases,想清楚逻辑. 坑:su...
本文逻辑 作者试图通过对SSCLI的探索,对于各种基本数据结构做一些比较与测试,试图找出各个数据结构之间的关系与最佳用法。 数据结构: Stack, Queue, ArrayList, List, SortedList, HashTable, Dictionary 如果您指向知道怎么用好,请跳到本文末尾查看 我眼中的最佳实践。 如果您对于数据结构的设计与原理感兴趣,不妨顺序读...

This stack structure is back by ArrayList. All operations are guaranted constant time performance. package main import "github.com/emirpasic/gods/stacks/arraystack" func main() { stack := arraystack.New() // empty stack.Push(1) // 1 stack.Push(2) // 1, 2 stack.Values() // 2, 1 ...
