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], 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

代码：

#include <bits/stdc++.h>
using namespace std;

int main() {
	int a1, a2, b1, b2, c1, c2;
	int a = 0, b = 0, c = 0, m;
	scanf("%d.%d.%d %d.%d.%d", &a1, &b1, &c1, &a2, &b2, &c2);
	c = c1 + c2;
	if(c >= 29) {
		m = c;
		c = m % 29;
		b = b + m/29;
	}
	b += (b1 + b2);
	if(b >= 17) {
		m = b;
		b = m % 17;
		a = a + m / 17;
	}
	a += (a1 + a2);
	printf("%d.%d.%d\n", a, b, c);
	return 0;
}
