cleanup array

A cleanup array is a tool used in programming to gather resources or tasks that need to be properly finished or released when a program ends or an object is no longer needed. It ensures that things like memory, files, or connections are correctly closed or freed, preventing leaks or errors. Think of it as a to-do list for tidying up after work, making sure everything is left in a good state for future use. It helps maintain efficiency, stability, and prevents resource exhaustion in software applications.
