TLE for only testcase 0

#1

Please check why my code is giving TLE for test case 0 but passing all the rest

#2

Your code can be optimized as :slight_smile:
1.after using prime sieve, simply collect all primes into another array or vector, so now for all test cases you just have to print n-1th index of that array!
eg prime_numbers [ ] = {2,3,5,11,13…}

#3

its working now
Thanks a lot for your help
