The worst case occurs in a linear search algorithm when:
  • The item is located in the middle of the array.
  • The item is not present in the array at all.
  • The item is the last element of the array.
  • The item is either the last element or is absent from the array.
The worst-case scenario for a linear search is when:
  • The search has to examine every element in the array.
  • This typically happens if the item is at the end or not in the array.
Thus, the worst case occurs when the item is the last element or is not present at all.
