Ch2 Simple Sorting And Searching Algorithm Pdf Array Data This document discusses algorithms for sorting and searching. it introduces algorithm analysis and why it is important to analyze algorithms to compare different solutions, predict performance, and set parameter values. Understanding sorting and searching algorithms is essential for gcse computer science students. these hands on activities reinforce key concepts, from linear and binary search to bubble, insertion, and merge sort.
Chapter Three Searching And Sorting Algorithm Pdf Computer Sorting algorithms: insertion sort selection sort shell sort bubble sort quick sort merge sort radix sort – searching: linear search–binary search. Very basic and simple search algorithm. in linear search, we search an element or value in a given array by traversing the array from the starting, til. the desired element or value is found. it compares the element to be searched with all the elements present in the array and when the element is matched successfully, it returns the index of the . Selection sort is the only algorithm where we decide the *final* resting spot of a value. if we are running the algorithm and the selected index is 5 currently, then we know indexes 0 4 are sorted and their values will not change. A divide and conquer sorting algorithm that repeatedly breaks down a list into sublists until each sublist consists of a single element and merges those sorted sublists until it results into a sorted list. study with quizlet and memorize flashcards containing terms like average case, best case, execution count and more.

Selection sort is a sorting algorithm that starts by finding the smallest item on the list and then swaps it with the first element of the list. then it finds the smallest element in the remaining list (ignoring the first one) and swaps it with the second element on the list. I can explain why computers need to search data and perform a linear search to find the position of an item in a list. i can identify when a binary search can be used and perform its steps on a set of data. i can compare and contrast linear and binary search and trace the code for both searching algorithms. Sorting refers to arranging data in a specific order, typically in ascending or descending order. it helps in efficient searching, data analysis, and enhances the performance of other algorithms. these algorithms compare elements to determine their order. bubble sort (o (n²)) – simple but inefficient for large data. The document discusses linear search and binary search algorithms. linear search sequentially checks each element of a list to find a target value, having worst case linear time complexity.
