The worst case occurs in linear search algorithm when ____
|
Item is not in the array at all
|
|
Item is somewhere in the middle of the array
|
|
Item is the last element in the array or item is not there at all
|
|
Item is the last element in the array
|
Explanation:
Detailed explanation-1: -The worst case occurs in the Linear Search Algorithm when the item to be searched is in end of the Array.
Detailed explanation-2: -For Linear Search, the worst case happens when the element to be searched (x) is not present in the array. When x is not present, the search() function compares it with all the elements of arr[] one by one. Therefore, the worst-case time complexity of the linear search would be O(n).
Detailed explanation-3: -Time Complexity of Linear Search The worst-case time complexity is O(n), if the search element is found at the end of the array, provided the size of the array is n.
