Solution: Bitonic Array Maximum

## Problem Statement

Find the maximum value in a given Bitonic array. An array is considered bitonic if it is first monotonically increasing and then monotonically decreasing.

In other words, a bitonic array starts with a sequence of increasing elements, reaches a peak element, and then follows with a sequence of decreasing elements. The peak element is the maximum value in the array.

**Example 1**:
```
Input: [1, 3, 8, 12, 4, 2]
Output: 12
Explanation: The maximum number in the input bitonic array is '12'.
```
**Example 2**:
```
Input: [3, 8, 3, 1]
Output: 8
```

**Example 3**:
