Study Notes
- An array is a collection of items stored at contiguous memory locations.
- Items in an array can be accessed using an index.
- Binary search is a search algorithm that finds the position of a target value within a sorted array.
- Binary search works by repeatedly dividing the search interval in half.
- Bubble sort is a sorting algorithm that repeatedly steps through a list.
- Bubble sort compares adjacent elements and swaps them if they are in the wrong order.
- A concrete step is a detailed action in an algorithm that specifies exactly how to perform a task.
- A count-controlled loop repeats a specific number of times.
- Count-controlled loops are controlled by a counter variable (e.g., "for" loop).
- Desk checking is a manual method of reviewing the logic of a program or algorithm.
- Desk checking uses pencil and paper instead of a computer.
- An event-controlled loop continues to execute until a specific condition or event occurs.
- Event-controlled loops can be triggered by user input or a sensor reading.
- Heterogeneous describes a collection of items that are of different types.
- Homogenous describes a collection of items that are all of the same type.
- Index is a numerical representation of an element's position within an array or list.
