Hello Everyone I am NB from Claws of Python. In this video we're going to learn about Linear Search.
A linear search or sequential search is a method for finding an element within a list. It sequentially checks each element of the list until a match is found or the whole list has been searched.
We have been given a list of n elements. And we need to search for an element given by the user let's call it as key.
The basic approach is go through the entire list from beginning and compare each element with key.
If we find the element return the index of the element or return -1 if we reach the end of the list.
Let's say we have 5 elements in the list
[5, 42, 12, 79, 102]
key is 79.
So we need to search for 79.
we start searching from the beginning and compare each element with key.
5 != 79
42!= 79
12!= 79
79== 79 we found ther key at index 3... so we will return 3 from the Linear search function.
Here is how you can implement Linear search function in Python.
U can also implement this linear search function in any other language but logic remains same.
I will link linear search implentations in different languages in the description.
