This function determines if a variable is a member of an array.
|
|
The variable can be a string, fixnum, or array.
|
|
|
|
*Examples:*
|
|
|
|
member(['a','b'], 'b')
|
|
|
|
Would return: true
|
|
|
|
member(['a', 'b', 'c'], ['a', 'b'])
|
|
|
|
would return: true
|
|
|
|
member(['a','b'], 'c')
|
|
|
|
Would return: false
|
|
|
|
member(['a', 'b', 'c'], ['d', 'b'])
