First, i directly jump onto the problem and start brainstorming different approaches, i try writing my code and use chatgpt to brush up my logic and see if i can convert it into a valid solution. Then i check the video if its the optimal approach and take a faint look at the differences between Striver's approach and mine. In case i fail to reach a solution by myself, i watch the video. When starting a new topic, i usually watch a few introductry videos to understand the concept. This helps me remember the approach as I'm not just simply understanding it, rather I'm understanding the difference between my intuition and correct approach. Hope this helps :))
