@听取WA声一片5 这样

#include<iostream>
using namespace std;
int month[]={0,31,29,31,30,31,30,31,31,30,31,30,31};
int main(){
    int x,y;
    int s,c,n=0;
    cin>>x>>y;
    for(int i=1;i<=12;++i){
        for(int j=1;j<=month[i];++j){
            c=(j%10)*1000+(j/10)*100+(i%10)*10+(i/10);
            s=c*10000+i*100+j;
            if(s<x||s>y) continue;
            n++;
        }
    }
    cout<<n;
}
