Study Notes
Computational Thinking
- Definition: A thought process that helps solve problems like computers do.
-
Key Principles:
- Abstraction: Focusing on the most relevant aspects of a problem, ignoring unnecessary details. Example: Creating a website – focusing on design and functionality, not every line of code.
- Decomposition: Breaking down a complex problem into smaller, more manageable tasks.
- Pattern Recognition: Identifying and using repeating patterns in data.
Linear vs. Binary Search Algorithms
-
Linear Search:
- When to use: Unsorted lists, smaller data sets.
- How it works: Starts from the beginning and checks each item until the target is found.
-
Binary Search:
- When to use: Sorted lists, larger data sets.
- How it works: Divides the list in half repeatedly, narrowing down the search space.
Real-World Example: Movie Streaming
- Linear Search: Browsing a list of movies from the beginning, scrolling down until you find your choice.
- Binary Search: Quickly finding your movie by continuously dividing the list and narrowing down the options.
Algorithm Efficiency
- Evaluation: Assessing how quickly a search algorithm finds a desired item, a measure of efficiency.
- Linear Search is less efficient when dealing with larger data sets.
- Binary Search is more efficient for larger data sets.
