Question

Which array element does the sequential search algorithm first look at?

Short answer

Answer: The first element with index 0 (the first element) in the array.

Step-by-step solution

Understanding Sequential Search

A sequential search algorithm is a simple search method that goes through an array or a list element by element, comparing each element with the target value until a match is found or the end of the array is reached.

Identify the first element looked at

In the sequential search algorithm, the search starts with the first element of the array. So, the first array element that the sequential search algorithm looks at is the element with the index 0 (assuming zero-based indexing).

Answer

The sequential search algorithm first looks at the element with index 0 (the first element) in the array.
