Handicapped Multiplication

# Handicapped Multiplication
# This is a drill, just to cultivate creativity in programming practices, particularly algorithmic design.
# There are more efficient ways to do multiplication in any language, so this function is not designed to be used elsewhere.

# Objective: create a method for multiplying two integers using only the operators / and +

function hm(x::Int64, y::Int64)
    s = 0

    while x > 0
        if isodd(x); s += y; end
        x = div(x, 2)
        y += y
    end

    return s
end

# Alternatively, the challenge could be modified so that the operators /n and *n are used, where n is an integer greater than 1.
