The purpose of this task is to learn how you think through a problem, how you approach finding a solution, and how you iterate over ideas.
As you work on these tasks we want to hear what you're thinking and attempting. It's fine to make a mistake. It's fine to try things and realize they don't work. You're not expected to get it just right on your first attempt.
Ask questions as you have them, and be prepared to discuss your choices when you are done.
- In your programming language of choice, write code that will print a 12 by 12 multiplication table.
Example Output:
1 2 3 4 5 6 7 8 9 10 11 12
2 4 6 8 10 12 14 16 18 20 22 24
3 6 9 12 15 18 21 24 27 30 33 36
4 8 12 16 20 24 28 32 36 40 44 48
5 10 15 20 25 30 35 40 45 50 55 60
6 12 18 24 30 36 42 48 54 60 66 72
7 14 21 28 35 42 49 56 63 70 77 84
8 16 24 32 40 48 56 64 72 80 88 96
9 18 27 36 45 54 63 72 81 90 99 108
10 20 30 40 50 60 70 80 90 100 110 120
11 22 33 44 55 66 77 88 99 110 121 132
12 24 36 48 60 72 84 96 108 120 132 144
- Modify the function to allow the multiplication table to be formatted so each number is right aligned
Example Output (align: :right):
1 2 3 4 5 6 7 8 9 10 11 12
2 4 6 8 10 12 14 16 18 20 22 24
3 6 9 12 15 18 21 24 27 30 33 36
4 8 12 16 20 24 28 32 36 40 44 48
5 10 15 20 25 30 35 40 45 50 55 60
6 12 18 24 30 36 42 48 54 60 66 72
7 14 21 28 35 42 49 56 63 70 77 84
8 16 24 32 40 48 56 64 72 80 88 96
9 18 27 36 45 54 63 72 81 90 99 108
10 20 30 40 50 60 70 80 90 100 110 120
11 22 33 44 55 66 77 88 99 110 121 132
12 24 36 48 60 72 84 96 108 120 132 144
- Modify the function to print a formatted multiplication table of any size, taking a min and max for arguments.
Example Output (min: 9, max: 13, align: :right):
81 90 99 108 117
90 100 110 120 130
99 110 121 132 143
108 120 132 144 156
117 130 143 156 169
- Modify the function to accept a string to use as a delimiter between numbers in each row
Example Output (delimiter: " |", align: :right):
1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12
2 | 4 | 6 | 8 | 10 | 12 | 14 | 16 | 18 | 20 | 22 | 24
3 | 6 | 9 | 12 | 15 | 18 | 21 | 24 | 27 | 30 | 33 | 36
4 | 8 | 12 | 16 | 20 | 24 | 28 | 32 | 36 | 40 | 44 | 48
