Bsc CSIT Semester 3 – Data Structure and Algorithms – Unit 7: Searching and Hashing (6 Hrs.)

Hash Table Definition A Hash Table is a data structure that stores data in an array and allows fast insertion, deletion, and searching by using a hash function to compute an index. Example If keys

Definition Binary Search is an efficient searching algorithm used to find an element in a sorted array or list. It works by repeatedly dividing the search interval into two halves. Key Requirement

1. Hashing (Definition) Hashing is a technique used to store and retrieve data efficiently using a hash table. - A hash function converts a key into an index (address) in the hash table. - It allo

1. Definition Binary Search is an efficient searching algorithm that works on a sorted array. It repeatedly divides the search interval into half and compares the middle element with the target valu

1. Given Information - Hash table size (m) = 5 - Hash function: \[ h(x) = x \% 5 \] - Keys to insert: {0, 1, 2, 4, 5, 7} --- 2. Linear Probing Definition Linear Probing resolves collisions

Definition Sequential Search (also called Linear Search) is a simple search technique where each element of a list is checked one by one until the desired element is found or the list ends. Character

1. Hashing (Definition) Hashing is a technique used to map data items (keys) to fixed-size values using a mathematical function called a hash function. It allows fast insertion, deletion, and search
