1058. A+B in Hogwarts (20)

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：极简单，10分钟内包括题目和代码都可以搞定。

#include <iostream>
using namespace std;

int main(int argc, const char * argv[]) {
int a1, b1, c1, a2, b2, c2, a, b, c;
scanf("%d.%d.%d", &a1, &b1, &c1);
scanf("%d.%d.%d", &a2, &b2, &c2);
b1 += (c1 + c2) / 29;
c = (c1 + c2) % 29;
a1 += (b1 + b2) / 17;
b = (b1 + b2) % 17;
a = a1 + a2;

printf("%d.%d.%d\n", a, b, c);

return 0;
