Learn DSA patterns in Python first, then translate to Java once a pattern clicks. Organized by the 15 core patterns — not by problem number.
- Learn the logic in Python (fast to write, less boilerplate). Once a pattern clicks, redo 2-3 problems of that same pattern in Java.
- Every problem you solve, ask "what pattern is this?" before you code. That's the actual skill interviewers test.
