Regarding Devops

I want to understand the DevOps role in detail. What exactly does a DevOps engineer do in day-to-day work? How much DSA (Data Structures and Algorithms) is required for a DevOps role? Is strong DSA mandatory, or are basic problem-solving skills enough? What is the future scope of DevOps in the coming years? If someone here is currently working as a DevOps professional, please guide me with the right direction and insights.
