Indices - cycles?

Здравейте, може ли пояснение относно условието на задачата Indices:
The full sequence is generated by performing these actions until you reach an index that is outside the bounds of the array ARR. Of course cycles are absolutely possible. When a cycle is started in the sequence it may never reach any index that is outside the bounds of the ARR.

Какво точно се разбира под цикъл?

На всяка позиция намираш кой е индекса на следващата позиция :slight_smile:
