NO CODE just written algorithm

Horse Movers Next week, you have to move several horses across town. Each horse is in its own stall which is enclosed with a door in the front. In the back of the stall is a tag with the horses name and weight. You cannot remove the tag.

Today you have been asked to develop an algorithm that will allow you to determine the average weight of all of the horses, and the name and weight of the lightest horse and the heaviest horse.

You may assume that:

there aren't any other people around to help you gather the information about each horse;

you can weigh only one horse at a time;

and you cannot remove horses from their stables to weigh them (you'll need a portable scale).

Develop an algorithm that does not require writing down or recording the name and/or weight of every horse. Instead, you want to record only the minimum amount of information needed at any one time to solve this problem.

Submit the algorithm that calculates: the number of horses the average weight of all horses the name and weight of the lightest horse the name and weight of the heaviest horse the specific pieces of data that youll need to complete your algorithm. Please remember than an algorithm must be unambiguous, executable, and terminating.
