Questions & Step-by-Step Solutions
Which of the following conditions must be true for binary search to work?
Step 1: Understand what binary search is. It is a method used to find a specific value in a list (array) of numbers.
Step 2: Know that binary search works by repeatedly dividing the list in half.
Step 3: Realize that for binary search to work correctly, the list must be sorted. This means the numbers should be in a specific order, either from smallest to largest or largest to smallest.
Step 4: If the list is not sorted, binary search will not be able to find the value correctly because it relies on the order of the numbers.
