hey, try median bucket sort, its 2n log n, ie, first linear median search O(n) then split the elements to two buckets, repeat for sub-buckets

Just a quick question, after finding the average of index, if that mid position happens to land on the target index, does the search stop and the target is found?

I watched previously the video where you explain the Big-O Notation, in it you showed ant the end that in a "IF -> ELSEIF -> ELSE" the time complexity would be O(n^2). At 2:47 there was an "IF -> ELSEIF -> ELSE" why is the time complexity in this case O(log n) and not O(n^2)?

Whats the purpose of returning specifically -1 if the target value is not found? Why not simply state that the target wasnt found?
@MichaelSambol

Why not return array[mid], why return mid I don't understand
@MichaelSambol
@MichaelSambol Год назад
The code returns the index/location of the element you're searching for: github.com/msambol/youtube/blob/master/search/binary_search.py.
@maxheinwal5084
@maxheinwal5084 4 месяца назад
if you return array[mid], you would return the number you are looking for, because mid is the index of the wanted number.

There are 14 numbers in this LIST.. so Average should be (0,14)=7
@MichaelSambol
@MichaelSambol Год назад
It's by index in the array... so 0 and 13. See code here: github.com/msambol/dsa/blob/master/search/binary_search.py
