import java.util.Scanner;
public class KboatDDARowSwap
{
public static void main(String args[]) {
Scanner in = new Scanner(System.in);
int arr[][] = new int[4][4];
System.out.println("Enter elements of 4x4 array ");
for (int i = 0; i < 4; i++) {
System.out.println("Enter Row "+ (i+1) + " :");
for (int j = 0; j < 4; j++) {
arr[i][j] = in.nextInt();
}
}
System.out.println("Input Array:");
for (int i = 0; i < 4; i++) {
for (int j = 0; j < 4; j++) {
System.out.print(arr[i][j] + "\t");
}
System.out.println();
}
//Swap 0th and 3rd rows
for (int j = 0; j < 4; j++) {
int t = arr[0][j];
arr[0][j] = arr[3][j];
arr[3][j] = t;
}
System.out.println("Swapped Array:");
for (int i = 0; i < 4; i++) {
for (int j = 0; j < 4; j++) {
System.out.print(arr[i][j] + "\t");
}
System.out.println();
}
}
}
