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 [0,107], 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
简析:和乙级的一道题类似,主要是把减改成了加,然后有个测试点会错因为int不够,得用long long。
#include<iostream>
using namespace std;
int main()
{
long long n[2] = {0};
long long a, b, c;
for (int t = 0; t < 2;t++)
{
scanf("%d.%d.%d", &a, &b, &c);
n[t] = c + b * 29 + a * 17 * 29;
}
long long n1 = n[1] + n[0];
a = n1 / (29 * 17);
cout << a<<'.';
n1 = n1 % (29 * 17);
b = n1 / 29;
cout << b << '.';
c = n1 % 29;
cout << c;
return 0;
}
