Banner Program ISC Computer Science 2018 Practical

The names of the teams participating in a competition should be displayed on a banner vertically, to accommodate as many teams as possible in a single banner.

Design a program to accept the names of N teams, where 2 < N < 9 and display them in vertical order, side by side with a horizontal tab (i.e. eight spaces).

Test your program for the following data and some random data:

Example 1:
INPUT:
N = 3
Team 1: Emus
Team 2: Road Rols
Team 3: Coyote
OUTPUT:

E       R       C
m       o       o
u       a       y
s       d       o
                t
        R       e
        o
        l
        s

Example 2:
INPUT:
N = 4
Team 1: Royal
Team 2: Mars
Team 3: De Rose
Team 4: Kings
OUTPUT:

R       M       D       K
o       a       e       i
y       r               n
a       r       R       g
l       s       o       s
                s
                e

Example 3:
INPUT:
N = 10
OUTPUT:
INVALID INPUT

import java.util.Scanner;

class Banner{

    public static void main(String[] args) {

        Scanner in = new Scanner(System.in);

        System.out.print("N = ");

        int n = Integer.parseInt(in.nextLine());

        if(n < 3 || n > 8){

            System.out.println("INVALID INPUT");

            return;

        }

        String a[] = new String[n];

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

            System.out.print("Team " + (i + 1) + ": ");

            a[i] = in.nextLine();

        }

        String l = a[0];

        for(int i = 1; i < a.length; i++){

            if(l.length() < a[i].length())

                l = a[i];

        }

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

            for(int j = 0; j < n; j++){

                if(i < a[j].length())

                    System.out.print(a[j].charAt(i) + "\t");

                else

                    System.out.print("\t");

            }

            System.out.println();

        }

    }

}
