    Study Notes

    Sorting and Searching Algorithms

    Quicksort

    • Quicksort is a sorting algorithm that splits a list into two sublists, according to a pivot element, and recursively sorts them.
    • The basis of Quicksort is the divide-and-conquer approach.
    • Binary search can be used on sorted lists only.
    • The list size affects the performance of Binary search, with larger lists taking longer to search.

    Java Interfaces for Searching and Sorting

    • In Java, the java.util.List interface is used for binary searching.
    • The java.util.Comparable and java.util.Comparator interfaces are used for sorting.

    Time Complexity of Quicksort

    • The best-case time complexity of Quicksort is O(n log n), making it efficient compared to other sorting algorithms.
    • The main disadvantage of using Binary search on unsorted lists is that it will not work correctly.

    Java Interface for Binary Searching

    • In Java, the java.util.List interface is used for binary searching, and it can specify the search key.

    Space Complexity of Quicksort

    • The space complexity of Quicksort is O(log n), making it more memory-efficient than Mergesort.
    • The main advantage of using Binary search on sorted lists is its efficiency, with a time complexity of O(log n).
