Pattern 20

Given an integer n. You need to recreate the pattern given below for any value of N. Let's say for N = 5, the pattern should look like as below:

*        *
**      **
***    ***
****  ****
**********
****  ****
***    ***
**      **
*        *

Print the pattern in the function given to you.

Example 1

• Input : n = 4
• Output :

*      *
**    **
***  ***
********
***  ***
**    **
*      *

Example 2

• Input : n = 2
• Output :

*  *
****
*  *

Constraints

1 <= n <= 100

Fun facts

• This problem demonstrates the concept of loops and pattern recognition/matching which is a fundamental aspect in many software applications.
• In the real-world, pattern generation problems like this are commonly used in computer graphics and game development to generate textures, shapes, or terrain.
• It is also used in tools like regular expression engines which are widely used in text parsing, syntax highlighting, data validation, and search functionalities which are core to numerous software applications.
• Interesting fact: Algorithms to generate complex patterns are also pivotal in certain aspects of cryptography and data security.
