Find Bitonic Peak

Explore how to identify the peak element in a bitonic sequence, where values first rise then fall, by implementing a binary search algorithm. This lesson guides you through the logic and Python code needed to efficiently find the peak while minimizing the search space compared to linear methods.

We'll cover the following...

In this lesson, we will be given an array that is bitonically sorted, an array that starts off with increasing terms and then concludes with decreasing terms. In any such sequence, there is a “peak” element which is the largest element in the sequence. We will be writing a solution to help us find the peak element of a bitonic sequence.

A bitonic sequence is a sequence of integers such that: x0<...<xk>...>xn1x_0 < ... < x_k > ... > x_{n-1} ...
