Questions and Answers

What is Binary Search?

A sorting algorithm that sorts elements by selecting a pivot and partitioning the array
A searching algorithm used in a sorted array by repeatedly dividing the search interval in half (correct)
A searching algorithm that compares each element of the array with the target element
A sorting algorithm that sorts elements by repeatedly swapping adjacent elements

What are the conditions for applying Binary Search in a data structure?

The data structure must be unsorted and access to any element of the data structure takes linear time
The data structure must be sorted and access to any element of the data structure takes constant time (correct)
The data structure must be sorted and access to any element of the data structure takes linear time
The data structure must be unsorted and access to any element of the data structure takes constant time

What is the time complexity of Binary Search?

O(N)
O(log N) (correct)
O(N^2)
O(1)

When should Binary Search be used?

When searching a large dataset that is sorted and stored in contiguous memory (A) Signup and view all the answers

What are the basic steps to perform Binary Search?

Set the low index to the first element of the array and the high index to the last element, set the middle index to the average of the low and high indices, decide the next search space based on the value of the key and the middle element, repeat until the target element is found or the search space is exhausted (B) Signup and view all the answers

What is the difference between Iterative and Recursive Binary Search?

Iterative Binary Search uses a loop to repeatedly divide the search interval in half, while Recursive Binary Search uses function calls to do the same (C) Signup and view all the answers
