B - Median Pyramid Easy

• 
• Thoughts.
  • When two steps, the top is 2.
  • the time for disasters (similar to ‘the witching hour’ but not midnight)
    • 3 in a normal arrangement.
    • For example, 5 1 2 4 3 would be two, so the top would be 2.
    • Similarly, we can do the same for 4.
  • the time of the four stages of life (birth, old age, disease, death)
    • 7 1 2 6 3 4 5 and the top is 2 2 3 4 4 which is 3
  • Hypothesis: Top only moves in the range of median plus or minus 1?
• Official Explanation
  • Hypothesis is incorrect.
  • If two squares have the same value, then the two squares above them have the same value, regardless of the other squares.
    • When thinking about specifics, it’s not a good idea to think only about the bottom layer, where the different values are lined up.
    • Once you’re in a certain state, you can’t get out.
    • Median → What if two values are the same?
• problem partitioning - median - Repeated results of the same operation
