hello @anshulgurawalia

a) build ur sieve only once, u r bulding new sieve for every new test case due to which ur program is slow

b) also u need to prepare ur sieve atleast of size 10^6+1

#3

i have change my code as you said but it is doesnot pass 1 test case i think it is due to array declaration as globally please take a look

#4

ur sive size is small , preare ur sieve atleast upto 10^6+1

#5

i have change the size but it doesnot pass the test case please edit my code

now u need to optimise it furthure

store all prime numbers upto 10^6 in some array/vector
and then answer each query in O(1) using that vector
