Please let me know how you prefer this kind of problem-solving videos.

  • Record from the beginning. Start reading the problem, think, solve, code (example). Shows complete journey of solving a problem. Very lengthy videos.
  • Record after theoretically solving (like what I did here). It can possibly lead to an incorrect solution and getting AC in next tries.
  • Solve and get AC, then record the video and describe the solution and implementation. Short and concise
