Expert Solution

Step 1

Question 2A:

Since the given inputs are

SAT = "Sat"

SUN = "Sun"

The input will be only valid when we enter only Sat and Sun

the while condition : while day!=SAT and day != SUN: will check for both Sat and Sun and will return if it is true either it will again ask for input.
