Questions & Step-by-Step Solutions
What is the primary condition for using binary search on a dataset?
Step 1: Understand what binary search is. It is a method used to find a specific value in a dataset.
Step 2: Know that binary search works by repeatedly dividing the dataset in half.
Step 3: Realize that for binary search to work correctly, the dataset must be sorted. This means the values should be in a specific order, like from smallest to largest.
Step 4: If the dataset is not sorted, binary search will not be able to find the target value efficiently or at all.
