What are the main advantages of using string compression techniques?
- Enhanced string representation in user interfaces, simplified data retrieval, and improved database querying.
- Higher computational overhead, better support for complex data structures, and improved sorting algorithms.
- Improved data storage efficiency, reduced bandwidth usage, and faster data transmission.
- Increased complexity in data processing, enhanced encryption, and better random access performance.
The main advantages of using string compression techniques include improved data storage efficiency, reduced bandwidth usage, and faster data transmission. By eliminating repeated characters, the compressed string requires less space, making it beneficial in scenarios with storage or bandwidth constraints.
Can the longest common substring problem be solved using the greedy approach? Why or why not?
- No, because the greedy approach is not suitable for substring-related problems.
- No, because the greedy approach may make locally optimal choices that do not result in a globally optimal solution.
- Yes, because the greedy approach always leads to the globally optimal solution.
- Yes, but only for specific cases with small input sizes.
The longest common substring problem cannot be efficiently solved using the greedy approach. Greedy algorithms make locally optimal choices, and in this problem, a globally optimal solution requires considering the entire input space, making dynamic programming or other techniques more suitable.
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.
