Which type of search is more efficient than a linear search for sorted data?

• A. Exponential Search
• B. Linear Search
• C. Binary Search
• D. Selection Search

Answer: (C)

Binary search is more efficient than a linear search for sorted data because it significantly reduces the number of comparisons needed to find an element. In a linear search, each element in the list is checked one by one until the target element is found, which can result in a time complexity of O(n), where n is the number of elements in the list. On the other hand, binary search operates by dividing the sorted list in half with each iteration. First, it compares the target element to the middle element of the list. If the target is less than the middle element, the search continues in the lower half; if it's greater, it moves to the upper half. This halving process reduces the search space logarithmically, leading to a time complexity of O(log n). Consequently, binary search can significantly speed up the search process in sorted data compared to linear search. While other options may refer to methods of searching, they do not operate with the efficiency of binary search on sorted data.
