Algorithm Fourth Edition: 1.1.27 binomial distribution, from 10 to 10 billion@ TOC Recursive method to realize binomial distribution operation, O(2^N) The recursive algorithm is relatively simple. It is very suitable for small parameters. But the problem is also obvious. N * k > 100 is very slow at the beginning. When > 1000, the progr ...

Before ECMASCript 6, constructor patterns and prototype patterns and their combinations were used to simulate the behavior of classes. However, these strategies have their own problems and corresponding compromises. The implementation of inheritance can also be very lengthy and confusing. Therefore, ECMASCript5 introduces a new class keyword to ...
