Quick Search Algorithm in Data Structure And Algorithm : Practice MCQ Questions & Answers with Explanations

Using Quick search algorithm, searching starts from the leftmost character and finds the first occurrence of the pattern "CAT" at index 6.

During the searching phase, comparisons can be done in any order. It has quadratic worst-case behaviour but good practical behaviour.

If the pattern occurs in the text, the worst case running time of Boyer-Moore's algorithm is O(mn).

Boyer-Moore's algorithm uses both good-character and bad-character shift tables, whereas Quick search uses only bad-character shift tables.

Quick search algorithm starts searching from the leftmost character to the right, and uses only bad-character shift tables.

The space complexity of the Quick search algorithm is O(n), where n represents the input size.

Quick search algorithm uses only bad-character shift tables, which is one of the reasons for its increased speed over Boyer-Moore's algorithm.

The time complexity of the Quick search algorithm is O(m+n), which is proven to be faster than Boyer-Moore's algorithm.

Quick search algorithm was developed to overcome the drawbacks of Boyer-Moore's algorithm, improving speed and efficiency.

Quick search algorithm is the fastest algorithm in the string matching field, whereas linear search searches for an element in an array sequentially.
