Q 1. Type Conversion: House of Cards
 
You and your friends are building several houses of cards. You have N cards in total.
 
A house of cards is like a pyramidal building.
Hence, a house of cards with a single level will be made of just two cards forming a triangle.
The one with two levels will have four cards forming two triangles at the first level, one card sitting on top of them, and then two cards forming a triangle at the second level.
Thus it takes 7 cards to build a house of cards with two levels.
 
Given your N cards, you first try to build the house of cards with the maximum number of levels and then try to build another house with the remaining cards and so on until you have no cards remaining or no more houses can be made.

You need to find out how many houses you can build.
 
Example
N = 24. Then, you will be able to make a house of three levels with 15 cards, a house of two levels with 7 cards, and a house of one level with 2 cards. Hence, the answer is 3.
 
Note
You will get inputs as they are from stdin and you will have to typecast them into required types.
