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.
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.
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.
Input: 3 1/2 3/4 3/4 Output: 4
Input: 5 1/2 3/4 1/2 1/4 1/4 Output: 4
plz take care of the new line ,and checking for minimality is a must
Leppy said on the forums: Using getchar leads to many wrong answers. The end of line may or may not be \r\n which is two characters. Just use scanf instead and pull the 0 and 2 character.
