What is the algorithmic complexity of searching for elements in an array?

The algorithmic complexity of searching for elements in an array depends on the type of search:

• Linear search — sequentially checking each element. Complexity: O(n), where n is the number of elements in the array.
• Binary search — applied to a sorted array, dividing the search interval in half each time. Complexity: O(log n).

Example: if the array is unsorted, you may need to check all elements in the worst case (O(n)). If the array is sorted, binary search allows you to find an element much faster, reducing the number of checks.
