백준 - 비밀번호 찾기( 17219번, JAVA )

Hash ( https://www.acmicpc.net/problem/17219 )

풀이

• 그냥 기본적인 HashMap의 put(), get() 메소드들 쓸 수 있는지 물어보는 문제

package problem_solving.greedy;

import java.util.Collections;
import java.util.PriorityQueue;
import java.util.Scanner;

public class BaekJoon_3135 {

	public static void main(String[] args) {
	package problem_solving.hash;

import java.util.HashMap;
import java.util.Scanner;

public class BaekJoon_17219 {

	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		int n = Integer.parseInt(sc.next());
		int m = Integer.parseInt(sc.next());
		HashMap<String, String> hm = new HashMap<>();
		for(int i= 0 ; i <n ; i++) {
			hm.put(sc.next(), sc.next());
		}
		
		for(int i= 0 ; i < m ; i++) {
			
			String key = sc.next();
			System.out.println(hm.get(key));
			
		}
	}

}
