Question

The linear search algorithm should be coded using a __________ loop because we are interested in the index of an item in a list.

A) For
B) While
C) Do-While
D) For Each

Answer 1

The linear search algorithm is best implemented with a for loop as it helps in tracking the index of an item in a list and allows early termination if the item is found.

Step-by-step explanation:

The linear search algorithm should be coded using a for loop because we are interested in the index of an item in a list. When using a for loop, you have a built-in index variable that is automatically incremented with each iteration, which is beneficial for tracking the index position within the array or list.

If the search item is found, the loop can be terminated early using a break statement, and the current index can be returned or used to indicate the position of the item. If the loop completes without finding the item, it indicates that the item is not in the list.
