I have done an assignment question which asks me to find the average case of pentary search. The one I came up with is:
C(n) = C(n/5) + 14/5
However, I got it wrong and the professor didn't really explain why.
Can you help me?
Pentary search is dividing the array into 5 parts and look for a specific key.
These are the number of comparisons made by the computer from pentary search.
Adding all possible comparisons I get 14 over 5 slots. This is why I have 14/5
