Topics in Searching

1. Core Idea of Searching

  • Searching is used to locate a key in a collection of elements.
  • The result of searching tells whether the key is present or absent.
  • If the key is present, the position of the key can also be found.
2

2. Linear Search

  • Linear search is the most fundamental and simplest search method.
  • It is an exhaustive technique: every element is compared one by one with the key.
  • The comparison begins at the first element and moves towards the last element.
3

3. Binary Search

  • Binary search uses the ordering of elements in a sorted list.
  • It compares the key with the middle element of the sorted list.
  • There are three possibilities: the middle element matches the key, is greater than the key, or is less than the key.
4

4. Search by Hashing

  • Hashing is used to know the presence of a key in just one step.
  • A hash function generates an index value for every element and creates a hash table.
  • Each index in the hash table holds only one item.
