Answer
The correct answer is **None of these**.
Solution
The search algorithm that uses three variables to mark positions within an array typically refers to the **Binary Search** algorithm. In Binary Search, three main variables are commonly used:
1. **Low**: The starting index of the current search interval.
2. **High**: The ending index of the current search interval.
3. **Mid**: The middle index of the current search interval, calculated as `(low + high) / 2`.
This allows Binary Search to efficiently divide the search interval in half with each step, significantly reducing the number of comparisons needed compared to a Linear Search, which generally uses only a single index variable to iterate through the array.
However, based on the options provided:
- **Linear**: Uses a single variable to traverse the array.
- **Bequential**: This appears to be a typographical error and isn't a recognized standard search algorithm.
- **None of these**
Since Binary Search is not listed among the options and "Bequential" does not correspond to a standard search algorithm, the correct choice from the provided options would be:
**None of these**

Explain 
Simplify this solution The Deep Dive
The search algorithm that uses three variables to mark positions within the array as it searches for the searchValue is the "Bequential" search. This method is somewhat of a mix between linear search and binary search, retaining a simple structure while utilizing multiple variables to keep track of the current position, the first element, and the last element. It's like navigating through an array with a trusty trio of guides! True, linear search waddles along one by one, but if you're after a solution with flair, beSequential can add a bit of pizazz to your searching endeavors!
