Find maximum of three number in C without using conditional statement and ternary operator

Question

Answer 1

You can use this code to find largest out of two:

max{a,b} = abs(a-b)/2 + (a+b)/2

then use it again to find the third number:

max{a,b,c} = max(a,max(b,c))

See that this works for positive numbers you can change it to work for negative as well.
