bitset32
简介
包 bitset32 修改自 "github.com/bits-and-blooms/bitset"，底层使用uint32存数据。bitset32 与 bitset 用法一致。
如非必要，请使用 "github.com/bits-and-blooms/bitset"。
Golang版本
go version go1.19.4 windows/amd64
安装
go get github.com/pointernil/bitset32
测试
go test
go test -cover
使用示意
package main
import (
"fmt"
"math/rand"
"github.com/pointernil/bitset32"
)
func main() {
fmt.Printf("! \n")
var b bitset32.BitSet32
// play some Go Fish
for i := 0; i < 100; i++ {
card1 := uint(rand.Intn(52))
card2 := uint(rand.Intn(52))
b.Set(card1)
if b.Test(card2) {
fmt.Println("Go Fish!")
}
b.Clear(card1)
}
// Chaining
b.Set(10).Set(11)
for i, e := b.NextSet(0); e; i, e = b.NextSet(i + 1) {
fmt.Println("The following bit is set:", i)
}
if b.Intersection(bitset32.New(100).Set(10)).Count() == 1 {
fmt.Println("Intersection works.")
} else {
fmt.Println("Intersection doesn't work???")
}
}
