Chirag is a pure Desi boy. And his one and only dream is to meet Santa Claus. He decided to decorate a Christmas tree for Santa on coming Christmas. Chirag made an interesting Christmas tree that grows day by day. 

The Christmas tree is comprised of the following

---> Parts

---> Stand

Each Part is further comprised of Branches. Branches are comprised of Leaves. 

How the tree appears as a function of days should be understood. Basis that print the tree as it appears on the given day. Below are the rules that govern how the tree appears on a given day. Write a program to generate such a Christmas tree whose input is a number of days. 

Rules: 

If tree is one day old you cannot grow. Print a message "You cannot generateChristmas tree"

Tree will die after 20 days; it should give a message "Tree is no more"

Tree will have one part less than the number of days. 

E.g. 

On 2nd day tree will have 1 part and one stand. 

On 3rd day tree will have 2 parts and one stand 

On 4th day tree will have 3 parts and one stand and so on.

Top-most part will be the widest and bottom-most part will be the narrowest.

Difference in number of branches between top-most and second from top will be 2

Difference in number of branches between second from top and bottom-most part will be 1

Below is an illustration of how the tree looks like on 4th day
