#include<bits/stdc++.h>
using namespace std;
int a[10086];

    int l,m,x,y,s=0;
    cin>>l>>m;

            a[i]++;
    }

      if (a[i]==0)

把

for (int i=1;i<=l;i++)
          if ((i>=x)&&(i<=y))
            a[i]++;
    }

改成

for(i=0;i<=l;i++){
        if(a[i]==0){
            sum++;
        }
    }

试试

我后面那个改的中有sum++，你把sum改成你设的s就行，自测ok
