Complete the function that returns a christmas tree of the given height. The height is passed through to the function and the function should return a list containing each line of the tree.

XMasTree(5) should return : ['____#____', '___###___', '__#####__', '_#######_', '#########', '____#____', '____#____']
XMasTree(3) should return : ['__#__', '_###_', '#####', '__#__', '__#__']

Pad with underscores (_) so each line is the same length. Also remember the trunk/stem of the tree.

Examples

The final idea is for the tree to look like this if you decide to print each element of the list:

n = 5 will result in:

____#____              1
___###___              2
__#####__              3
_#######_              4
#########       -----> 5 - Height of Tree
____#____        1      
____#____        2 - Trunk/Stem of Tree

n = 3 will result in:

__#__                  1
_###_                  2
#####          ----->  3 - Height of Tree
__#__           1
__#__           2 - Trunk/Stem of Tree
