+Task 1: Brilliant Numbers
+Submitted by: Mohammad S Anwar
+
+Write a script to generate first 20 Brilliant Numbers.
+
+ || Brilliant numbers are numbers with two prime factors of the same length.
+
+The number should have exactly two prime factors, i.e. it’s the product of two 
+primes of the same length.
