NHF – new heroes for Heroes V 3.1.

The sum of the squares of the legs is equal to the square of the hypotenuse.

The catch isn't in that:smile52:.

I think this function will work. It returns the index with the smallest value.

function min(array)
	local l = length(array);
	local index = {};
	local r;
	for i1, n1 in array do
		index[i1] = 0;
		for i2, n2 in array do
			if n1 < n2 then
				index[i1] = index[i1] + 1;
			end;
		end;
	end;
	for i, c in index do
		if c == l - 1 then
			r = i;
		end;
	end;
	return r;
end;

Assuming that the index of the argument passed to the function is the name of a city, and the value is the distance. That is, it will return the name of the nearest city (from those in the array).
