Hello /prog/, I have a challenge for you.
It's called spiral numbers. Being the expert programmers you are you've probably already have heard of it, but if not it goes a little something like this:
Here's some more examples from my own implementation written in snake tongue.
It's called spiral numbers. Being the expert programmers you are you've probably already have heard of it, but if not it goes a little something like this:
Given two positive integers a and b, output on the screen a rectangle with width = b numbers and height = a rows, containing the numbers from 1 to a*b in a spiraling fashion, as shown below. For a = 4 and b = 3, the output is:
1 2 3
10 11 4
9 12 5
8 7 6
The columns must be properly n+1 positions, where n is the number of digits in the decimal representation of a *b.
Write a program that prompts for a and b and then displays the appropriate rectangle of numbers.
Example:
If a = 3 and b = 4, the above rectangle should be
1 2 3 4
10 11 12 5
9 8 7 6Here's some more examples from my own implementation written in snake tongue.
Have fun!
