Write a program that reads a positive integer n from the user and prints out a nxn multiplication table. The columns should be spaced by a tab.

Your program should interact with the user exactly as it shows in the following example: Please enter a positive integer: 10 1 2 3 4 5 6 7 8 9 10 2 4 6 8 10 12 14 16 18 20 3 6 9 12 15 18 21 24 27 30 4 8 12 16 20 24 28 32 36 40 5 10 15 20 25 30 35 40 45 50 6 12 18 24 30 36 42 48 54 60 7 14 21 28 35 42 49 56 63 70 8 16 24 32 40 48 56 64 72 80 9 18 27 36 45 54 63 72 81 90 10 20 30 40 50 60 70 80 90 100

Note: The output should be in columns and rows format eg: 1 2 3 4 5 6 7 8 9 10

2 4 6 8 10 12 14 16 18 20
