Concept of Searching: Searching is the process of finding a particular item or element within a collection of items. It involves examining each element in the collection until the desired item is found. Sequential Search: Also known as linear search. Involves checking each element in a list or array one by one from the beginning until the target element is found or the end of the list is reached. Simplest form of searching. Works well for small lists or unsorted data. Time complexity is O(n) where n is the number of elements in the list. Index Sequential Search: Enhances the efficiency of sequential search by using an index. The index is a data structure containing pointers or references to the elements in the main data structure (e.g., array). The index allows for quicker access to elements, reducing the number of comparisons needed. The search first checks the index to locate the block where the target element might be, then performs a sequential search within that block. Suita...
