Hi,

Check your prime sieve code. Initially all elements are considered to be prime. But you have initialised 0 to all numbers.

#3

I am still not able to get it. Please help!!

#4

try to submit this:

#5

Now 2/3 test cases are passing and the 3rd test case is showing TLE.

#6

Actually in your code of prime sieve the outer loop is for(int i=3;i<=100005;i+=2) but it should be
for(int i=3;i*i<=100005;i+=2)

#7

It is still giving TLE

#8

You are calling prime sieve again and again for every testcase. That is why, it is giving tle. You should precompute kth prime before queries.
