Chapter 7.11, Problem 7.20CP
Explanation of Solution
Difference between sequential search and binary search:
| Sequential search | Binary search |
| Linear search or sequential search is the process of searching for a particular element that is present in the array one by one till the last element in the search element is found. | Binary search is a smart search process that searches for the particular element that is present in the array from the middle towards the left or right until the search element is found. |
| The search uses a loop that iterates from the beginning till the last element to find the search element. |
The search element is searched from the middle as the elements present in the array need to be present in the sorted order... |
