Strange Pair

A pair of strings form a strange pair if both of the following are true:

• The 1st string's first letter = 2nd string's last letter.
• The 1st string's last letter = 2nd string's first letter.

Create a function that returns True if a pair of strings constitutes a strange pair, and False otherwise.

Examples

is_strange_pair("ratio", "orator") ➞ True
# "ratio" ends with "o" and "orator" starts with "o".
# "ratio" starts with "r" and "orator" ends with "r".

is_strange_pair("sparkling", "groups") ➞ True

is_strange_pair("bush", "hubris") ➞ False

is_strange_pair("", "") ➞ True

Notes

It should work on a pair of empty strings (they trivially share nothing).
