Question

to search an element in a list and display the frequency of element present in list and their location using Linear search by using user defined function in python

Answer 1

Answer:

Problem: Given an array arr[] of n elements, write a function to search a given element x in arr[].

Examples :

Input : arr[] = {10, 20, 80, 30, 60, 50, 110, 100, 130, 170} x = 110; Output : 6 Element x is present at index 6 Input : arr[] = {10, 20, 80, 30, 60, 50, 110, 100, 130, 170} x = 175; Output : -1 Element x is not present in arr[].

A simple approach is to do 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 elements, return -1.
