Medium
- Key strategies
You can improve the design and implementation of algorithms to improve program performance. The following are some best practices:
- Use the correct data structure: Selecting a proper data structure can greatly improve the algorithm efficiency. For example, you can use a hash table to quickly search for elements and use an array to quickly access elements.
- Reduce memory allocation: Memory allocation is a time-consuming operation. You can pre-allocate memory or reuse allocated memory.
- Reduce the number of loops: Loops are a common algorithm structure. However, too many loops will deteriorate program performance. You can use more efficient algorithms.
- Use parallel computing: For some compute-intensive algorithms, use parallel computing to improve program performance. You can use multi-thread or distributed computing.
