WebMay 10, 2024 · For example, an array with 10 elements would make at most 4 comparisons for a binary search vs. 10 for a linear search—not such a big improvement. However, for an array with 1,000,000 elements, the worst case in binary search is only 20 comparisons. That's a huge improvement over linear search! WebFor example, if you have a few contacts with the same name, then they will all fit your search criteria. At other times, there might only be an approximate answer or no answer at all. In the most common case, you’ll be searching by value, which compares elements in the collection against the exact one you provide as a reference. flynn coins
