@final_deterrence

#include<iostream>
using namespace std;
int main()
{
    int l,m;
    cin>>l>>m;
    bool a[l+1];
    for(int i=0;i<=l;i++)
    {
        a[i]=1;
    }
    int s,e;
    for(int i=1;i<=m;i++)
    {
        cin>>s>>e;
        for(int j=s;j<=e;j++)
        {
            a[j]=0;
        }
    }
    int sum=0;
    for(int i=0;i<=l;i++)
    {
        sum+=a[i];
    }
    cout<<sum;
}

以A求关谢谢

@final_deterrence 目测是你代码b数组开小了

@Greeper 改大后还是不行┻┳|･ω･)，而且把O2优化关掉后#8就能过
