Answer 1

Think simple... Python example....

def bigger(a,b): #Find the bigger of two numbers ...
    if a > b:
        return a
    else:
        return b

def biggest(a,b,c): #Find the biggest of three numbers ...
    return bigger(a,bigger(b,c))

def median(a,b,c): #Just dance!
    x = biggest(a,b,c)
    if x == a:
        return bigger(b,c)
    if x == b:
        return bigger(a,c)
    else:
        return bigger(a,b)
