How is the Edit Distance algorithm typically used in practice?
- Convert a string to lowercase.
- Determine the length of the longest common subsequence between two strings.
- Measure the similarity between two strings by counting the minimum number of operations required to transform one string into the other.
- Sort a list of strings based on their lexicographical order.
The Edit Distance algorithm is used to measure the similarity between two strings by counting the minimum number of operations (insertions, deletions, or substitutions) required to transform one string into the other. It finds applications in spell checking, DNA sequencing, and plagiarism detection.
In DFS, which data structure is commonly used to keep track of visited nodes?
- Hash Table
- Linked List
- Queue
- Stack
In DFS, a stack is commonly used to keep track of visited nodes. As the algorithm explores a path as deeply as possible before backtracking, a stack is ideal for maintaining the order of nodes to be visited.
Recursive implementation of binary search involves breaking the problem into _______ subproblems until a solution is found.
- Five
- Four
- Three
- Two
Recursive implementation of binary search involves breaking the problem into two subproblems at each step, making it a logarithmic algorithm with a time complexity of O(log n), where 'n' is the number of elements.
