A single car can accommodate at most 4 people.
N friends want to go to a restaurant for a party. Find the minimum number of cars required to accommodate all the friends.
For each test case, we are given the number of friends going to the party.
Clearly, for less than 4 friends 1 car is sufficient. Using this logic we can deduce that for N friends the minimum cars required will be: $(N/4)$$+1$
O(1) for each test case.
