Linear Search in Python using while-loop, function, and recursion with algorithm and simple explanation.

Apr 7, 2025 · Explanation: A simple approach is to do a linear search, i.e. Start from the leftmost element of arr[] and one by one compare x with each element of arr[]. If x matches with an element, return the index. If x doesn’t match with any of the elements, return -1. Using Iterative Approach. This takes an array arr and a target element to search.

The given Python program demonstrates the implementation of linear search. It takes an array arr and a target element target as input. The linear_search() function iterates through each element of the array using a for loop.

Nov 7, 2024 · The iterative approach is probably the easiest way to understand linear search. You loop through the list, checking each element until you find the target or reach the end. First, we’ll create our function: We’ll loop through each element …

Nov 4, 2021 · In this article, we will implement a linear search algorithm to find the index of an element in a list in python. What is a linear search algorithm? In the linear search algorithm, we start from the index 0 of a list and check if the element is present at the index or not. If the element is present at the index, we return the index as output.

Nov 3, 2022 · Implement linear search following the below steps: Traverse the list/array using a loop. In every iteration, associate the target value with the given value of the list/array. If the values match, return the current index of the list/array. Otherwise, move on to the next array/list element. If no match is found, return -1.

Mar 9, 2024 · Method 3: Using a While Loop. The while loop continues to execute a block of statements as long as the condition is true. In the context of a linear search, the while loop can be used to scan through the list until the element is found or end of …

Feb 28, 2021 · We are creating a function for linear search that takes in two arguments. The first argument is the list that contains the items and the second argument is the target item that is to be found. Then, we are creating a loop with the counter i, i will hold all the indexes of the given list, i.e., i will go from 0 to length of the list – 1.

In this tutorial, we will learn the linear search in Python. we will write a code to search an element from a list. It compares each element to the criterion that we are finding. If all tiles are there, the element is located, and the algorithm returns the key’s index location.
