WebBinary search is used because it has a time complexity of O (N) for a sorted array. If we follow sequential access of Linked List, then it will take O (N) time to find the middle element. With this, the overall time complexity of Binary Search on Linked List will become O (N * logN). This will slower than linear search.

WebSep 7, 2024 · The time complexity of binary search on linked list is O (log n) which is much better than linear search which takes linear time O (n) to search an element, but for binary to work properly the given must be sorted. Its time complexity is less than O (n) because it does not check every element of the given list. WebJun 10, 2024 · For Example: time complexity for Linear search can be represented as O(n) and O(log n) for Binary search (where, n and log(n) are the number of operations). The Time complexity or Big O notations for some popular algorithms are listed below: Binary Search: O(log n) Linear Search: O(n) Quick Sort: O(n * log n) Selection Sort: O(n * n)
