Algorithm
Problem Name: Python -
In this HackerRank Functions in PYTHON problem solution,
In Python, a string of text can be aligned left, right and center.
.ljust(width)
This method returns a left aligned string of length width.
>>> width = 20
>>> print 'HackerRank'.ljust(width,'-')
HackerRank----------
.center(width)
This method returns a centered string of length width.
>>> width = 20
>>> print 'HackerRank'.center(width,'-')
-----HackerRank-----
.rjust(width)
This method returns a right aligned string of length width.
>>> width = 20
>>> print 'HackerRank'.rjust(width,'-')
----------HackerRank
Task
You are given a partial code that is used for generating the HackerRank Logo of variable thickness.
Your task is to replace the blank (______) with rjust, ljust or center.
Input Format
A single line containing the thickness value for the logo.
Constraints
The thickness must be an odd number.
0 < thickness < 50
Output Format
Output the desired logo.
