Finding the minimum value... (not math.min)

[Robin]

bartbes's is better.

Or, again:

Code: Select all

function get_min(t)
    min = math.min(unpack(t))
    for i, v in ipairs(t) do
        if v == min then
            return v, i
        end
    end
end

I LOVE programming because it's almost impossible to have only one solution to a specific problem!

[appleide]

Code: Select all

function min_index(first, ...)
	return math.min(first, ...) == first and 1 or min_index(...) + 1
end

function test(...)
	print(min_index(...))
end

test(1, 2, 3, 4) -- prints 1

test(4, 3, 1, 5, 6, 7) -- prints 3

Who needs for loops 8-)
