```Complicating a simple expression

Coding Exercise: Complication

Assume that the grader defines two variables A and B for you. Write a
program which prints out the value
min(A, B)

However, there is a catch: your program is not allowed to use the min
function. Instead, use max in a clever way to simulate min.

Hint, Method 1
What is max(-A, -B)?
Hint, Method 2
What is min(A, B)+max(A, B)?

My last code that worked somewhat
-----------------------------------
Original = max(A, B)
Opposite = max(-A, -B)

------------------------------------
Did not pass tests. Please check details below and try again.
Results for test case 1 out of 5
Before running your code: We defined A equal to 62 and B equal to 36.

Program executed without crashing.
Program output:

26

Expected this correct output:

36

A    B        Max(A, B)    Min(A, B)    Min(A, B)+Max(A, B)    Max(A,
B)+Max(A, B)    Min(A, B)+Min(A, B)
