Your logic of checking prime is completely illogical.
Please refer this for better understanding and it is much faster method of generating primes.

@vikashkmr519
we just need to find all the prime numbers between a and b in less time and count them.
Sieve Algo gives the prime number till n,here just generate prime between a and b,then count the number of primes.
