Completed today's problems: ✔️ Kadane's Algorithm

@ayesha_fatiima The biggest issue I face with whatsapp is it's enormous storage leftovers after receiving Media files, I would recommend Telegram because even after deleting the files from the phone the Files can be redownloaded anytime.... WhatsApp should be replaced with telegram.
