first round was coding round : 1. One string rotaion of other 2. Nearest largest and smallest prime value of given input. interview questions:What is difference between reference variable and pointer ?

Question

Accepted Answer

public class Main

{

//Find nearest large and small prime number

public static void main(String[] args) {

int start=6,dest=17;

int largest=Integer.MIN_VALUE;

int smallest=Integer.MAX_VALUE;

if(dest<2){

smallest=2;

}

for(int i=dest-1;i>=start;i--){

if(check_prime(i)){

if(i>largest)

largest=i;

if(i

smallest=i;

}

System.out.println(largest);

System.out.println(smallest);

}

public static boolean check_prime(int n){

for(int i=2;i<=n/2;i++){

if(n%i==0){

return false;

}

return true;

}

public static boolean rotation(String s1,String s2){
 if(s1.length()!=s2.length()){
           return false;
       }
        Queue q1=new LinkedList<>();
        for(int i=0;i q2=new LinkedList<>();
        for(int i=0;i0){
           
            char ch=q2.peek();
            q2.remove();
            q2.add(ch);

             if(q2.equals(q1)){
                return true;
            }

            k--;
        }

        return false;
