kertymägeneraattori

A kertymägeneraattori, often translated as accumulation generator or capacity generator, is a concept primarily found in certain programming paradigms, particularly in functional programming and systems dealing with streams or sequences of data. It refers to a function or a construct that produces a sequence of values, where each subsequent value is generated based on an accumulation of previous values. This is distinct from a simple generator that might produce independent values.

The core idea is that the generator maintains an internal state, which is updated with each new value produced. This state, or "accumulation," is then used in the computation of the next value. For example, a kertymägeneraattori could be used to generate the Fibonacci sequence, where each number is the sum of the two preceding ones. The generator would hold the last two numbers in its state and use them to calculate the next.

In practical terms, this can be implemented using iterators, coroutines, or similar mechanisms that allow functions to pause their execution and resume later, preserving their internal state. This makes them efficient for generating potentially infinite sequences without storing all elements in memory simultaneously. The concept is valuable for tasks involving cumulative operations, running totals, or any process where the history of generated values influences future output.
