# Is binary search faster than linear?

Binary search is more efficient than linear search; it has a time complexity of O(log n). The list of data must be in a sorted order for it to work. A binary search works by finding the middle element of a sorted array and comparing it to your target element.Click to see full answer. Then, what is faster than a binary search?Binary search is faster than linear search except for small arrays. However, the array must be sorted first to be able to apply binary search. There are specialized data structures designed for fast searching, such as hash tables, that can be searched more efficiently than binary search.Likewise, is binary search always faster than sequential? If you have a sorted array that’s big, then a binary search would be faster than a sequential search. If you have a sorted array that’s small, then it’ll be better to use the sequential array. Considering this, what is difference between linear and binary search? A linear search scans one item at a time, without jumping to any item. In contrast, binary search cuts down your search to half as soon as you find the middle of a sorted list. In linear search, the worst case complexity is O(n), where binary search making O(log n) comparisons. Linear search uses sequential approach.What is the advantage of binary search over linear search?Advantages: Compared to linear search (checking each element in the array starting from the first), binary search is much faster. Linear search takes, on average N/2 comparisons (where N is the number of elements in the array), and worst case N comparisons. Binary search takes an average and worst-case comparisons.
