All test case failing

@kunaldude04 this question requires the knowledge of a particular concept called Sieve of eratosthenes, which is covered under the Number Theory section.
I’d have to ask you to hold on to this question until you reach that section in the course. Meanwhile, you can try other topics.

This is a special case which requires fast calculation of prime numbers. And Sieve of eratosthenes helps us calculate prime number in a faster manner as compared to the usual method.
