Chapter Summary

--- PAGE 1 --- Chapter 5 Sorting “Every one of today's smartphones has thousands of times more processing power than the computers that guided astronauts to the moon.” — Peter Thiel In this Chapter » Introduction » Bubble Sort » Selection Sort » Insertion Sort » Time Complexity of Algorithms 5.1 INTRODUCTION Sorting is the process of ordering or arranging a given collection of elements in some particular order. We can sort a collection of numbers in ascending (increasing) or descending (decreasing) order. If the collection is of strings, we can sort it in an alphabetical order (a-z or z-a) or according to the length of the string. For example, words in a dictionary are sorted in alphabetical order; seats in an examination hall are ordered according to candidates' roll number. We can also sort a list of students based on their height or weight. Imagine finding the meaning of a word from a di…
