Can anyone help me with this?
Tried a few things so as to stop losing time. Still getting WA.
My code reads,
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.ArrayList;
public class Main {
public static ArrayList<Integer> primes;
public static void main(String[] args) throws NumberFormatException, IOException {
generatePrimes();
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
int t = Integer.parseInt(br.readLine());
int low,high;
while (t-- > 0) {
String[] w = br.readLine().split(" ");
low=Integer.parseInt(w[0]);
high=Integer.parseInt(w[1]);
if(low<2){
low=2;
}
if(high<2){
high=2;
}
printPrimes(low,high);
System.out.print("\n");
}
}
private static void generatePrimes() {
boolean[] dataset= new boolean[100001];
primes=new ArrayList<>();
int i, j;
for(i=2;i<100001;i++){//Set all values to true
dataset[i]= true;
}
for(i=2; i<100001; i++){
if(dataset[i]){
for(j=2*i; j< 100001; j=j+i){
dataset[j]= false;
}
}
}
for(i=2; i<100001; i++){
if(dataset[i]){
primes.add(i);
}
}
}
private static void printPrimes(int low, int high) {
for (Integer val : primes){
if(val>=low && val<=high){
System.out.println(val.toString());
}
}
}
}
I guess there might be an issues regarding pretty printing
