11. Selection Sort

Sorting is crucial for efficient searching and statistical analysis, where sorted data allows for fast retrieval of information and easier subsequent calculations. Selection sort is presented as a basic sorting algorithm that iteratively selects the smallest elements and organizes them in order, either through creating a new list or swapping elements in place. The algorithm has a time complexity of O(n²), making it less efficient for larger datasets.

    Selection Sort

    Selection Sort is a simple sorting algorithm that sorts an array by repeatedly selecting the smallest (or largest) element and moving it to a new position.

  • 11.1.2

    Strategy For Sorting

    This section covers Selection Sort, a fundamental sorting technique that organizes elements in an array by repeatedly identifying the smallest (or largest) element and moving it to its correct position in the sorted list.

    Illustration Of Selection Sort

    Selection sort is a simple sorting algorithm that repeatedly selects the smallest element from the unsorted portion of the list and moves it to the beginning.
