Question
The Worst case occur in linear search algorithm when*1 pointA) Item is somewhere in the middle of the arrayB) Item is the last element in the array or is not there at allC) Item is the last element in the arrayD) Item is not in the array at all
Solution
The worst case occurs in the linear search algorithm when the item is the last element in the array or is not there at all.
Here's why:
-
Linear search algorithm works by sequentially checking each element in the array until a match is found or the whole array has been searched.
-
If the item is the last element in the array, the algorithm has to go through every single element in the array before it finds the match. This means it has to do the maximum amount of work possible, making this the worst-case scenario.
-
Similarly, if the item is not in the array at all, the algorithm still has to go through every single element in the array before it can conclude that the item is not there. Again, this is the maximum amount of work the algorithm can possibly do, making it another worst-case scenario.
