a) Write a c++ function that takes in 3 integer inputs and returns true if there is some arithmetic expression (only using (), +, * or integer /) using the 3 integers in any order that results in 24.

b) Extend the above function to take in 4 integer inputs and return true if there is some arithmetic expression (only using (), +, * or integer /) using the 4 integers in any order that results in 24.
