How many linear searches will it take to find the value 7 in the list [1, 4, 8, 7, 10, 28]?
A
2
B
3
C
4
D
5
Explanation: 

Detailed explanation-1: -4 is the correct option. In Linear Search, every element in the list gets checked in each iteration of the loop that is traversing every element of the list.

Detailed explanation-2: -At the most, linear search algorithm takes n comparisons. In terms of implementation, linear search algorithm takes 2n+1 comparisons ( n to check if target element is found and n+1 comparisons to check if end of list is reached) in the worst case.

Detailed explanation-3: -Linear search is a sequential searching algorithm where we start from one end and check every element of the list until the desired element is found. It is the simplest searching algorithm.

Detailed explanation-4: -Start from the leftmost element of the list and one by one compare x with each element of the list. If x matches with an element, return True.
