How to Use

  • 01.Follow the pattern order. Don't jump to Graphs before Arrays.
  • 02.Focus on understanding why a pattern works, not memorizing code.
  • 03.Always write the Brute Force solution first, then optimize.
  • 04.If stuck for 45m, look at the solution, understand it, and re-code it.

Common Pitfalls

  • •Solving random LeetCode problems without a plan.
  • •Copy-pasting solutions to get the green checkmark.
  • •Skipping complexity analysis (Time/Space).
  • •Neglecting Easy problems (they build the intuition for Hards).
