Logic To Find Biggest of 3 Numbers using Binary Minus Operator

If user enters a = 1, b = 2, c = 3;

We check if a – b > 0 and a – c > 0
i.e., 1 – 2 > 0 and 1 – 3 > 0
=> -1 > 0 and -2 > 0 (Both these conditions are false).
So a is not the biggest.

In else block we check if b – c > 0
=> 2 – 3 > 0
=> -1 > 0 (which is false)
So b is not the biggest.

In that case whatever number present in variable c is biggest.
