Write a function named has_parts, that takes four arguments (you can safely assume that all arguments will always be strings). When this function is called, it should determine if any two of the first three string values can be concatenated in any order to form the fourth string value. The function should return True or False depending on the argument values.

Example:

has parts('a' 'bc', 'def', 'defa) will return True because 'def' and 'a' can be concatenated to form 'defa' has parts (a 'bc, 'def, 'adef will return True because 'a' and 'def' can be concatenated to form 'adef" has_parts ('a 'bc, 'def, 'defb will return False because there is no way to combine by concatenation any two of the strings 'a, 'bc', and 'def) to form defb' has parts'abc', 'ab', 'aa)will return True because 'a' can be concatenated with itself to form 'aa
