# Program to print a inverse pyramid character pattern

Given a positive integer n, print the inverse pyramid pattern upto n rows as shown in the examples.

Examples :

```Input : 4
Output :

A B C D D C B A
A B C C B A
A B B A
A A

Input : 6
Output :

A B C D E F F E D C B A
A B C D E E D C B A
A B C D D C B A
A B C C B A
A B B A
A A
```

## Recommended: Please try your approach on {IDE} first, before moving on to the solution.

Below is the implementation for the pattern:
