Algorithm Interview Questions and Answers
Ques 11. Explain the concept of the Boyer-Moore algorithm.
The Boyer-Moore algorithm is a string-searching algorithm that efficiently finds the occurrence of a pattern within a text. It uses a preprocessing step to skip portions of the text when mismatches occur.
Ques 12. What is the difference between depth-first search and depth-limited search?
Depth-first search explores as far as possible along each branch before backtracking, while depth-limited search restricts the depth of exploration to a specified limit before backtracking.
Ques 13. Explain the concept of the Manhattan distance.
Manhattan distance, also known as L1 distance or taxicab distance, is the sum of the absolute differences between the corresponding coordinates of two points. It is often used in grid-based pathfinding algorithms.
Ques 14. What is the purpose of the Ford-Fulkerson algorithm?
The Ford-Fulkerson algorithm is used to find the maximum flow in a flow network. It can be applied to solve various optimization problems, such as network flow and bipartite matching.
Ques 15. Explain the concept of the two-pointer technique.
The two-pointer technique involves maintaining two pointers (indexes) that traverse an array or sequence at different speeds. It is often used in algorithms that involve searching for pairs, detecting cycles, or optimizing sliding window problems.
