@Rajput.apry I have refactored your whole logic, your sieve was wrong, i have corrected it, no need to make csum at all.

When ya just precomputed then you have to count in range thats all.
If you don’t have any query than mark it resolved and rate full!
Happy coding!

int N=sc.nextInt();
while(N>0){
int a=sc.nextInt();
int b=sc.nextInt();
int count = 0;
for(int i = a; i <= b; i++) {
if(p[i] == 0)
count++;
}
System.out.println(count);
N–;

p[0] = 1;
p[1] = 1;

}
}

}

}

#3

it is showing arrayindexoutof bound erreo

#4

@Rajput.apry try this, putting code here adds some unnecessary chars.

its okay,did it,thanks!
