A linear search is to be performed on the list:12, 6, 8, 1, 3How many searches would it take to find the number 1?
A
1
B
2
C
3
D
4
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: -A linear search runs in at worst linear time and makes at most n comparisons, where n is the length of the list. If each element is equally likely to be searched, then linear search has an average case of n+12 comparisons, but the average case can be affected if the search probabilities for each element vary.

Detailed explanation-3: -Linear searching is used when the list has only a few elements and when a single search is performed in an unordered list.

Detailed explanation-4: -Step 1: First, read the search element (Target element) in the array. Step 2: In the second step compare the search element with the first element in the array. Step 3: If both are matched, display “Target element is found” and terminate the Linear Search function.
