Write a program that prints the block letter “B” in a 7x7 grid of stars like this:

* *
* *

* *
* *

Then extend your program to print the first letter of your last name as a block letter in a 7X7 grid of stars.

Explanation:

The solution code is written in Python 3.

Firstly, create a output variable that holds an empty string (Line 1).

Create an outer loop that will loop over 7 times to print seven rows of stars (Line 2). In row 0, 3 and 6 (which are divisible by 3) will accumulate up to 5 stars using an inner loop (Line 4-5) whereas the rest of the row will only print two stars with each start followed by a single space (Line 8-9) using another inner loop.

At last, print the output (Line 12).
