# Write a function, called check24,
# that takes a list of arbitrary, unsorted integers that are less than 20
# and decides if any of the two numbers in the list sum to 24.
# The function will return 2 things (in order):
# 1. A list of strings of the two-numbers pairs that sum to 24. If no pairs sum to 24, return an empty list
# 2. The number of the two-number pairs returned
# (hint: this is a multi return function)
#
# A sample run would be
#
# print(check24([12, 16, 8, 19, 5]))
# [16-8, 19-5], 2
# note: 16-8 is the same as 8-16, thus return once
#
# You may assume the list is non-empty, no tie, and will only contain integers,
# but you may not make any other assumptions about the list.
