@HuTaoJiaZiBuJia 你的代码连输入都有问题:
cin>>t1,t2; ,你的思路也不对

@HuTaoJiaZiBuJia 孩子，多练吧，

#include<bits/stdc++.h>
using namespace std;
int a[10001],s[101],e[101];
int main()
{
    int L,M;
    int ans=0;
    cin>>L>>M;
    for(int i=0;i<M;i++)
    {
        cin>>s[i]>>e[i];
        for(int j=s[i];j<=e[i];j++)
        {
            a[j]=1; 
        }
    }
    for(int i=0;i<=L;i++)
    {
        if(a[i]==0)
        {
            ans++;
        }
    }
    cout<<ans;
    return 0;
}

@HuTaoJiaZiBuJia wo以前写的，可以看一下~```c

include<bits/stdc++.h>

using namespace std; int main(){ bool a[10005]; int cnt=0; int l,n; cin>>l>>n; for(int i=0;i<=l;i++){ a[i]=1; } int x,y; while(n--){ cin>>x>>y; for(int i=x;i<=y;i++){ a[i]=0; } } for(int i=0;i<=l;i++){ if(a[i]==1){ cnt++; } } cout<<cnt; return 0; }
