/**
 * Write a program called TimeTable to produce the multiplication table 
 * of 1 to 9 as shown using two nested for-loops:
 * 
 *     |  1  2  3  4  5  6  7  8  9
 *   -------------------------------
 *   1 |  1  2  3  4  5  6  7  8  9
 *   2 |  2  4  6  8 10 12 14 16 18
 *   3 |  3  6  9 12 15 18 21 24 27
 *   4 |  4  8 12 16 20 24 28 32 36
 *   5 |  5 10 15 20 25 30 35 40 45
 *   6 |  6 12 18 24 30 36 42 48 54
 *   7 |  7 14 21 28 35 42 49 56 63
 *   8 |  8 16 24 32 40 48 56 64 72
 *   9 |  9 18 27 36 45 54 63 72 81
 * 
 * Modify the program to print the multiplication table of 1 to 12.
