买10送1
比如你有141元
先买140，送14
剩14+1=15
于是等价于15能买多少，形成递归

#include<bits/stdc++.h>

using namespace std;

#define ll long long

int main()
{
	ll t;
	cin >> t;

	while (t--) {
		ll m;
		cin >> m;
		ll plus = 0;
		ll temp = m;
		while (temp/10) {
			plus += temp / 10;
			ll l = temp/10;
			temp = temp % 10 + l;
		}
		cout << m + plus << endl;
	}
}
