A Tour of Go For continued

You can skip the index or value by assigning to _. If you only want the index, drop the ", value" entirely. package main import "fmt" func main() { pow := make([]int, 10) for i := range pow { pow[i] = i << uint(i) } for _, value

In fact, you can define a method on any type you define in your package, not just structs. You cannot define a method on a type from another package, or on a basic type. package main import ( "fmt" "math" ) type MyFloat float64 func (f

If the top-level type is just a type name, you can omit it from the elements of the literal. package main import "fmt" type Vertex struct { Lat, Long float64 } var m = map[string]Vertex { "Bell Labs": {40.68433,-74.39967}, "Google

累了就要写题解,最近总是被虐到没脾气. 来回最短路问题貌似也可以用DP来搞,不过拿费用流还是很方便的. 可以转化成求满流为2 的最小花费.一般做法为拆点,对于 i 拆为2*i 和 2*i+1,然后连一条流量为1(花费根据题意来定) 的边来控制每个点只能通过一次. 额外添加source和sink来控制满流为2. 代码都雷同,以HDU3376为例. #include <algorithm> #include <iostream> #include <cstring> #in

题目链接 Treeland Tour 题目就是让你求树上LIS 先离散化,然后再线段树上操作.一些细节需要注意一下. #include <bits/stdc++.h> using namespace std; #define rep(i, a, b) for (int i(a); i <= (b); ++i) #define dec(i, a, b) for (int i(a); i >= (b); --i) typedef long long LL; const int N =
