题解

设一个变量x，每移动一次就更新x

#include <iostream>
#include <cstdio>
using namespace std;
int main(){
	int t;
	cin >> t;
	while(t--){
		string a;
		cin >> a;
		int x = '1';
		int ct = 0;
		for(int i = 0; i < 4; i++){
			if(a[i] == '0'){
				a[i] = '9' + 1;
			}ct += max(a[i] - x, -a[i] + x) + 1;
			x = a[i];
		}cout << ct << endl;
	}

	return 0;
}
