EGYPIZZA - Pizza
Abotrika is having a party because his team won the African cup so he is inviting his friends to eat some pizza. Unfortunately, his friends can't eat an entire pizza but all of them know exactly how much pizza they can eat and insist on getting the exact amount of pizza but Abotrika eats one complete pizza and all of them wants his amount of pizza in one slice. Their requests break down to three different pizza slices-either one quarter or a half or three quarters of pizza.
Write a program that will help Abotrika to find out what is the minimal number of pizzas he has to order so that everyone gets exact amount of pizza they want.
Input
First line contains an integer N, 0 ≤ N ≤ 10 000, the number of friends. In each of next N lines there is amount of pizza that each of Abotrika's friends wants to eat, that is the fraction 1/4, 1/2 or 3/4.
Output
In the first and only line you should write the minimal number of pizzas Abotrika has to order don't forget to order one complete pizza for Abotrika.
Example 1
Input: 3 1/2 3/4 3/4 Output: 4
Example 2
Input: 5 1/2 3/4 1/2 1/4 1/4 Output: 4

If someone wants 3/4 you can only take 1/4 out and give him 3/4. He won't accept 3*(1/4) or 1/4+1/2 because 1/4 has been cut and merged.

Hint: 2*(1/4)!=(1/2) ;) |

can someone please tell me what's going on in the 9th test case? I wrote in C and I already checked all the test cases here in comment and had no problem, but still getting WA. Then I asked someone for a sample code written in c++, the idea was pretty much the same and it got AC. Is it because of the language or can someone who got AC after struggling with the 9th judge share their experience? |

For the given sample test case: 3 3/4 3/4 1/2, isn't the answer 3? 2 pizzas can be split as 3/4 3/4 1/2 and the remaining 1 for the host. Am I missing out something here? Last edit: 2018-07-06 09:44:31 |

For all those who are getting confused if these test cases are correct and then read my previous comment. That is what the actual scenario is!! |
