@[yangjinxuan123456](/user/1240784) 所有变量和数组初始化为 0
```cpp
#include<bits/stdc++.h>
using namespace std;
int l,n,a,b,c,ar[10010],cnt1=0,cnt2=0;
int main(){
cin>>l>>n;
for(int i=0;i<n;i++){
cin>>a>>b>>c;
if(!a){
for(int j=b;j<=c;j++){
if(ar[j]==1){
cnt1++;
cnt2--;
}
ar[j]=2;
}
}
else{
for(int j=b;j<=c;j++){
if(ar[j]==2){
ar[j]=1;
cnt2++;
}
}
}
}
cout<<cnt2<<endl<<cnt1;
return 0;
}
```
