import java.util.*;
public class Main {
public static void main(String args[]) {
Scanner scan = new Scanner(System.in);
int r=1,i=2;
int m=0;
int n1=scan.nextInt();
while(r<=n1){
int n = scan.nextInt();
int count=n;

int arr[] = new int[1000001];
arr[0]=0;
arr[1]=0;
for(int k =2;k<1000001;k++){
    arr[k]=1;}

while(i<=1000000){
     m=0;
    if(arr[i]==1){
        for(int j=2;j*i<=1000000;j++){
            if(arr[i*j]!=0)
            arr[i*j]=0;
        }
    }
    if(arr[i]==1){

m=i;
count–;
}
i++;
if(count==0)
break;
}

    System.out.println(m);
    
    i=2;

r++;

Hey @akashbisht7,
I have modified your code a little. Your approach was correct, just some slight errors. https://ide.codingblocks.com/s/151137
But there is one more mistake in this. So please find that and correct it. This code will give you answer only if, the answer is less than 1000.
Kindly find the mistake and try yourself. If you are stuck somewhere, feel free to ping me.
