1)Check prime Is A Number Prime
concept:- no divide hona chiya khud sa ya fir apena app sa toa n ko n number tak divde karka dekho then agar count 2 aya means 1 or apena app sa toa number is prime easy haa
1)for loop ;
2)int count = 0;
3)if check div horaha haa ke nahi t%i == 0;
4)if count==2 then prime;
public class HelloWorld{
public static void main(String []args){
System.out.println("Hello World");
int t = 114;
int count = 0;
for(int i = 1;i<=t;i++){
if(t%i==0){
count++;
};
};
if(count==2){
System.out.println("it is prime");
}else{
System.out.println("it is not prime");
}
}
}
import java.util.*;
public class Main{
public static void main(String[] args) {
Scanner scn = new Scanner(System.in);
int t = scn.nextInt();
for(int i = 1;i<=t;i++){
int n = scn.nextInt();
int tf = 0;
for(int j = 1;j<=n;j++){
if(n%j==0){
tf++;
}
}
if(tf ==2){
System.out.println("prime");
}
else{
System.out.println("not prime");
}
}
}
}
