解题思路:





注意事项:





参考代码:

import java.util.Scanner;

public class Main {

        static 

        Scanner sc = new Scanner(System.in);

        public static void C(int M,int[] array){

                for(int i=0;i<M;i++){

                        int A = sc.nextInt();

                        int B = sc.nextInt();

                        int temp = array[A-1];

                         array[A-1] = array[B-1];

                         array[B-1] = temp;

                }

                for(int i=0;i<array.length;i++){

                        System.out.println(array[i]);

                }

        }

        public static void main(String[] arg){

                 int N = sc.nextInt();

                 int M = sc.nextInt();

                 int[] array = new int[N];

                 for(int i=0;i<N;i++){

                        array[i] = sc.nextInt();

                }

                C(M, array);

        }
