题目

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]\left[0,10^{7}\right], Sickle is an integer in [0,17)[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:

1
3.2.1 10.16.27

Sample Output:

1
14.1.28

题解

思路

  • 就简单的加法
  • 处理一下进位
  • 完事儿

数据结构

  • A,B是原数
  • S是新数

算法

  • 先加
  • 再计算进位。

代码

  • 因为使用Python能ac，因此只放了Python的代码。

A, B = list(map(lambda x: x.split("."), input().split()))
S = [int(i) + int(j) for i, j in zip(A, B)]
if S[2] >= 29: 
    S[1] += 1
    S[2] -= 29
if S[1] >= 17: 
    S[0] += 1
    S[1] -= 17
print(".".join(list(map(str, S))))
