Q. Use the linear search program to search the key with value 8 in the list having duplicate values such as [42, -2, 32, 8, 17, 19, 42, 13, 8, 44]. What is the position returned? What does this mean?

Answer :-

Script of linear search is

def linearSearch(list, key):
    for index in range(0,len(list)):
        if list[index] == key:
            return index+1
            return None

lst = [42, -2, 32, 8, 17, 19, 42, 13, 8, 44]
key = 8
position = linearSearch(lst, key)
if position is None:
    print("Number",key,"is not present in the list")
else:
    print("Number",key,"is present at position",position)

Output :-

Number 8 is present at position 4
>>>

It mean that the linear search always tell the first position of element if that element is repeated more the 1 times.
