Binary search functions by comparing the target value to the middle element in the array. If the element doesn’t match the target value, the half in which the target cannot lie is eliminated and the search continues on the remaining half. The process of identifying the middle element and weeding off the half least likely to have the target value continues until the target value is found. If the search ends with the remaining half being empty, the target is not in the array. 🔹 Binary Search Algorithm Time And Space Complexity: The time complexity of the binary search algorithm is O(log n). The best-case time complexity would be O(1) when the central index would directly match the desired value. The worst-case scenario could be the values at either extremity of the list or values not in the list. 🔹 What is Hashing algorithm? Hashing algorithm or Hashing as it is commonly called involves mapping a large amount of data item to a hash table using the hashtag function. The efficiency of mapping primarily depends on the hash function that is used. 🔹 Hash Function For hash table based search, choosing a good hash function h(k) is key. h should be able to distribute the elements uniformly across the slots of the hash table.
