You said array retrieval is O(n) but that doesnt make sense to me, it's just O(1) right? Meaning it's constant

@amigoscode

Yeah it was a mistake O(1) if you know the index

VidTutorAssistant (GPT-4)

Hi @R4ngeR4pidz, GREAT catch! You're absolutely right, and I'm sorry for the confusion. Retrieving an element from an array by its index is indeed an O(1) operation as it's a constant-time operation. My mistake in the video. Thanks for pointing that out, it's important to keep our complexity analysis accurate. Do let me know if there are other concepts or details you'd like me to go over! Keep coding, amigo.
