1058 A+B in Hogwarts (20 分)
If you are a fan of Harry Potter, you would know the world of magic has its own currency system – as Hagrid explained it to Harry, “Seventeen silver Sickles to a Galleon and twenty-nine Knuts to a Sickle, it’s easy enough.” Your job is to write a program to compute A+B where A and B are given in the standard form of Galleon.Sickle.Knut (Galleon is an integer in [0,10
7
], Sickle is an integer in [0, 17), and Knut is an integer in [0, 29)).
Input Specification:
Each input file contains one test case which occupies a line with A and B in the standard form, separated by one space.
Output Specification:
For each test case you should output the sum of A and B in one line, with the same format as the input.
Sample Input:
3.2.1 10.16.27
Sample Output:
14.1.28
//和之前的一個B類題比較類似
#include <cstdio>
#include <cstring>
#include <cmath>
int main()
{
long long int Galleon1, Sickle1, Knut1;//中間結果用int的話可能溢位,索性全都用longlong了
long long int Galleon2, Sickle2, Knut2;//當然,中間計算的時候加個強轉也行
scanf("%lld.%lld.%lld", &Galleon1, &Sickle1, & Knut1);
scanf("%lld.%lld.%lld", &Galleon2, &Sickle2, &Knut2);
long long int sum = Galleon1 * 29 * 17 + Sickle1 * 29 + Knut1;
sum += Galleon2 * 29 * 17 + Sickle2 * 29 + Knut2;
printf("%lld.%lld.%lld", sum / 493, (sum / 29) % 17, sum % 29);
return 0;
