Write a function that implements linear search on a given list. This function should take a number

to be searched in the list, and the list itself as inputs and return true if the number is found in the

list, otherwise return false. Also, measure the time needed to run this function.

You should create a list that contains $10,000$ random elements in it $($hint: you can use

random.randint$()$ function from random module$).$
