Question

In Binary Search , which will be the scenario for Average Case performance ?

A. The 'Mid key’ is present, but it’s not the middle element O(logn).
B. The ‘input key’ is present, but it’s not the middle element O(logn).
C. The ‘Last key’ is present, but it’s not the middle element O(logn).
D. The ‘First key’ is present, but it’s not the middle element O(logn).​

Answer 1

Answer:

a principle in classical physics: the total mass of any isolated material system is neither increased nor diminished by reactions between the parts. — called also conservation of matter

Answer 2

Answer:

In binary search, there is an array containing multiple set of numbers.

These numbers are sorted in ascending or descending order and the algorithm states that when any numbered is provided for searching it in the array, then the array is divided into two halves.

After the array is divided, then it continues it's same algorithm to finally decide that whether the number is there or not.

In this search, the average case scenario is when the 'First key' is present, but it's not the middle element O(log n).
