Binary search is a search algorithm that finds the position of a target value within a sorted array.

• Start by comparing the target value with the middle element of the array.

• If the target value matches the middle element, return its position.

• If the target value is less than the middle element, search the left half of the array.

• If the target value is greater than the middle element, search the right half of the array.

• Rep...read more

The complexity of what?

• Please provide more context or specify what you are referring to

• Complexity can refer to various aspects such as technical, organizational, or project-related

• It can also be measured using different methods such as time, cost, or scope

Function to find the no. of times a sorted array has been rotated.

• Find the index of the minimum element in the array using binary search.

• The number of times the array has been rotated is equal to the index of the minimum element.

• Handle the case where the array is not rotated (minimum element at index 0).

Implementing a program with logarithmic complexity

• Use binary search instead of linear search

• Divide and conquer approach can be used

• Tree-based data structures can be used

• Examples: Binary search, Merge sort, Quick sort

Code for Binary Search

• Binary search is a divide and conquer algorithm

• It works by repeatedly dividing the search interval in half

• If the value is found, return the index

• If the value is not found, return -1

Test cases for function and binary search

• Test function with different input values and expected output

• Test binary search with sorted array and non-existent element

• Test binary search with unsorted array and existing element

• Test binary search with empty array

• Test binary search with array containing only one element
