process for problem solving#

• always read the problem statement twice.
  • ask clarifying questions
• try think of different ways to solve the problem
• think end-to-end of the best solutions based on complexity
• write the algorithm from patterns in drawing
• code it out
• try and improve it once you think you’re finished.
• go through other solutions (even if you answered correctly)
