The best way to go about this is always practice more and more, so I'd suggest start by discovering different ds/algo topics on geeks for geeks and then pick that topic and solve problems on leetcode starting from easy/medium to hard ones Pro tip: Initially it won't harm you to look for solutions if you are not able to solve intuitively and takes too long

Definitely, the designs only are not always very clear, and does not always convey the flow 100% correctly. It's better to have an interactive flow or maybe even a quick video tour through designs where designer explains the flows
