世界上最遥远的距离不是生与死，而是你亲手制造的BUG就在你眼前，你却怎么都找不到她。

$\color{red}{\text{AC = Answer Coarse = 粗劣的答案}}$

$\color{yellow}{\text{TLE = Time Limit Enough = 时间充裕}}$

$\color{green}{\text{MLE = Memory Limit Enough = 内存充裕}}$

$\color{cyan}{\text{CE = Compile Easily = 轻松通过编译}}$

$\color{blue}{\text{RE = Run Easily = 轻松通过运行}}$

$\color{purple}{\text{UKE = Unbelievably Keep Enough Score = 难以置信地保持足够的分数}}$

​数据千万条，清空第一条​。 ​多测不清空，爆零两行泪​。 ​清空不规范，超时总相伴​。

把下面这一坨粘到终端里

#!/bin/bash
while true; do
    #生成数据
    ./data > data.in
    #暴力
    ./bf < data.in > bf.out
    #疑似正解
    ./std < data.in > std.out
    #比较
    diff bf.out std.out > diff.txt
    #检查
    if [ -s diff.txt ]; then
        echo "false"
        exit 0
    else
        echo "true"
    fi
done
