读入优化

inline ll read(){
    ll x=0,p=1;char ch=getchar();
    while (ch<'0'||ch>'9'){if (ch=='-')p=-1;ch=getchar();}
    while (ch>='0'&&ch<='9'){x=(x<<1)+(x<<3)+ch-'0';ch=getchar();}
    return x*p;
}

输出优化

inline void write(ll x){
    char ch[L]={};int i=0;
    if (x<0) putchar('-');
    do{ch[++i]='0'+x%10;}while (x/=10);
    while (i)putchar(ch[i--]);
    putchar('\n');
}

随机数

#include <ctime>
using namespace std;
inline int get(int x){return rand()%x;}
int main()
{
    srand((unsigned)time(NULL));
    int n=get(32767);

win对拍

:loop
data.exe
std.exe
myp.exe
fc std.out myp.out
if errorlevel 1 goto end
goto loop
:end
pause

linux对拍

#!bin/bash
while true;
do
./data
./std
./myp
if diff std.out myp.out;then
echo AC
else
echo WA
exit 0
fi
done

C++对拍

终于还是学习了C++对拍的姿势，这样写可以比较时间而且win下和linux下都能跑，非常优秀

#include <iostream>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <algorithm>
#include <ctime>
#define rep(i,st,ed) for (int i=st;i<=ed;++i)

int main(void) {
    std:: ios:: sync_with_stdio(false);
    rep(i,1,100000) {
        printf("%d ",i);
        system("./data");
        double tt=clock();
        system("./std");
        std:: cout<<clock()-tt<<' ';
        tt=clock();
        system("./myp");
        std:: cout<<clock()-tt<<' ';
        if (system("diff std.out myp.out > NULL")==0) puts("AC");
        else {
            puts("WA");
            return 0;
        }
    }
    return 0;
}
