Prime visits doubt

#1

Please tell me the mistake in my code …

#2

Hi @G_rahil,
try modifying ur code. when an input n=2, l=0 and r=1 is given, ur code gives 2 as output i.e acc to ur code 0 and 1 are prime which is not true. Moreover, ur code is interpreting 2 as non prime.
Moreover, u are getting tle in one test case because the approach u r using to solve this problem is the naive approach. Try optimising ur code using sieve of eratosthenes.
Hope dis resolves ur doubt.
If u still face any problem, feel free to post it here.
