这是代码

#include<bits/stdc++.h>
using namespace std;

			idx=10+(int)(n[1]-'0');
		}else{
			idx=(int)(n[1]-'0');
		}
		ans++;
		if((int)(n[0]-'0')==0){
			x=true;
		}
	}
	if((int)(n[0]-'0')==0&&(int)(n[1]-'0')==0){
		ans++;
	}
	int y=false;
	if((int)(n[3]-'0')==2){

	}

		ans++; 
	}
	cout<<ans;
	return 0;
