Zigzag

Language/Type: C# recursion
Related Links:

Write a recursive method Zigzag that accepts an integer parameter n and that prints out n characters as follows. The middle character of the output should always be an asterisk ("*"). If you are asked to write out an even number of characters, then there will be two asterisks in the middle ("**"). Before the asterisk(s) you should write out less-than characters ("<"). After the asterisk(s) you should write out greater-than characters (">"). For example, the following calls produce the following output:

Call Output
Zigzag(1); *
Zigzag(2); **
Zigzag(3); <*>
Zigzag(4); <**>
Zigzag(5); <<*>>
Zigzag(6); <<**>>
Zigzag(7); <<<*>>>
Zigzag(8); <<<**>>>

Your method should throw an ArgumentException if passed a value less than 1. Note that the output does not advance to the next line.

Method: Write a C# method as described, not a complete program or class.
