Question

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        s        R        g
l                 o        s
                  s
                  e
                
Example 3:
INPUT:
N = 10
OUTPUT:
Invalid input.
