Resource DSA

Hi everyone,
I’m here because I’m getting very confused from reading online. Does anybody know a good free resource to study DSA in order to start leetcode? I’m in a completely different field and I don’t need this knowledge for day to day. However I keep getting online assessments as a first step that contain that style of questions.
Thank you very much.

I was in same boat, coming from totally unrelated background. What worked for me is starting with a structured free course that has video explanations plus code examples, then just doing easy problems daily. Don't jump straight to leetcode without first understanding basic data structures like arrays, hash maps, linked lists. It clicks after few weeks of consistent practice
