    my code:

    //Complete this code or write your own from scratch import java.util.; import java.io.;

    class Solution{ public static void main(String []argh) { Scanner in = new Scanner(System.in); HashMap dict = new HashMap<>();

        int n=in.nextInt();
    in.nextLine();
    for(int i=0;i<n;i++)
    {
        String name=in.nextLine();
        int phone=in.nextInt();
        dict.put(name, phone);
        in.nextLine();
    }
    while(in.hasNext())
    {
        String s=in.nextLine();
        if(dict.containsKey(s)){
            System.out.println(s+"="+dict.get(s));
        }
        else{
            System.out.println("Not found");
        }
    }
}

    }

    Simple solution

    class Solution{
	public static void main(String []argh)
	{
		Scanner in = new Scanner(System.in);
		int n=in.nextInt();
		in.nextLine();
        Map<String, Integer> mp = new HashMap<>();
		for(int i=0;i<n;i++)
		{
			String name=in.nextLine();
			int phone=in.nextInt();
            mp.put(name, phone);
			in.nextLine();
		}
        
		while(in.hasNext())
		{
			String s=in.nextLine();
            if (mp.containsKey(s)) {
                System.out.println(s + "=" + mp.get(s));
            } else {
                System.out.println("Not found");
            }
		}
	}
}
