Accumulator pattern

Keeping one name outside a loop - a total, a count, a largest so far - and updating it every round, so the loop remembers something about every value it has seen.

Depth 1 · Foundation

You can keep a running total, a count, a product or a largest-so-far in a loop, choose the start value that means "nothing seen yet", and spot a total that is reset inside the loop.
