#include <iostream>
#include <vector>
#include <algorithm>
using namespace std;
// A / b = C ... r, A >= 0, b > 0
vector<int> div(vector<int> &A, int b, int &r){
vector<int> C;
r = 0;
for(int i = A.size() - 1; i >= 0; i--){
r = r * 10 + A[i];
C.push_back(r / b);
r %= b;
}
reverse(C.begin(), C.end());
while (C.size() > 1 && C.back() == 0) C.pop_back();
return C;
}
int main(){
string a;
int b;
cin >> a >> b;
vector<int> A;
for(int i = a.size() - 1; i >= 0; i--){
A.push_back(a[i] - '0');
}
int r;
auto C = div(A, b, r);
for(int i = C.size() - 1; i >= 0;i--) cout << C[i];
cout << endl << r;
return 0;
}
守望先锋???这也能碰到?
哈哈哈哈哈哈哈,上勾拳!
