今天來解YKL12(UVA10170)：The Hotel with Infinite Rooms

The Hotel with Infinite Rooms

input:
第一個參數是S
第二個參數是D

output:
第D天的group size S

大概長下圖這樣

#include <iostream>

using namespace std;

int main(){
    long long S,D;
    while(cin >> S >> D){
        long long curr = 0;
        while(curr < D){
            curr += S;
            if(curr >= D){
                cout << S << endl;
                break;
            }
            S++;
        }
    }
    return 0;
}
