WebSep 30, 2024 · Binary search is more efficient in the case of larger datasets. Time Complexity Time complexity for linear search is denoted by O (n) as every element in the array is compared only once. In linear search, best-case complexity is O (1) where the element is found at the first index. WebThe Time Complexity of Binary Search: The Time Complexity of Binary Search has the best case defined by Ω(1) and the worst case defined by O(log n). Binary Search is the faster of the two searching algorithms. However, for smaller arrays, linear search does a better job. Example to demonstrate the Time complexity of searching algorithms:
