Important Takeaways from Leaving Certificate Computer Science: Algorithms What is an Algorithm?: An algorithm is a step-by-step process for solving problems, such as sorting or searching. The efficiency of an algorithm is determined by its time complexity (how long it takes to complete) and space complexity (how much memory it uses), which are essential concepts in Leaving Certificate Computer Science. Sorting Algorithms: Key sorting algorithms like Selection Sort, Insertion Sort, and Bubble Sort are fundamental for organizing data. While these algorithms work differently, Quick Sort and other advanced methods are preferred for larger datasets due to their efficiency. Search Algorithms: Understanding Linear Search and Binary Search is critical for locating elements within a list. Linear Search checks each item sequentially, while Binary Search, which requires sorted data, is much faster and more efficient for large datasets. Algorithmic Efficiency and Big O Notation: Big O Notation is used to measure the efficiency of an algorithm by examining how its time complexity or space requirements grow with input size. Mastery of Big O Notation is essential for comparing different algorithms and selecting the most efficient solution. Time Complexity and Best Practices: Understanding time complexity is vital in Leaving Certificate Computer Science. Algorithms like O(n) and O(n²) have different performance implications, so choosing the right algorithm for a given problem is crucial for optimizing performance and resource usage.
