Logarithmic Time Complexity
The reason binary search has a time complexity of O(log2 n) is because it divides the input size by 2 in each step. This halving process can be represented by a logarithmic function. In a list of size n, binary search can find an element in at most log₂(n) steps.
Why is Binary Search log n?
Binary search is a popular algorithm used to search for an element in a sorted list efficiently. In this article we can going to understand why binary search has a time complexity of O(log2 n).
