题目：

代码：

import java.util.Scanner;

public class Xingyuxingxi {
    public static void main(String[] args) {
       Scanner sc=new Scanner(System.in);
       int a= sc.nextInt();
       int [][]b=new int[a][a];
       int [][]c=new int[a][a];
        for (int i = 0; i < a; i++) {
            for (int j = 0; j < a; j++) {
                b[i][j]= sc.nextInt();
            }
        }
        for (int i = 0; i < a; i++) {
            for (int j = 0; j < a; j++) {
                c[j][i]= b[i][j];
            }
        }
        for (int i = 0; i < a; i++) {
            for (int j = 0; j < a; j++) {
                if(j!=0)
                {
                    System.out.print(" ");
                }
                System.out.print(c[i][j]);
            }
            System.out.println();
        }
    }
