2.ReentrantReadWriteLock锁降级 我们前面刚学习了JAVA并发编程——Synchronized与锁升级,今天我们来学习一下锁降级。 我们先来看一下ReentrantReadWriteLock锁的定义: 一个资源能别多个读线程访问,或者被一个写线程访问。 也就是说: 读读不互斥 写写互斥 读写互斥 只有在读多写少情境之下,读写锁才具有较高的性能...

Sure, here is a simple implementation of the Quick Sort algorithm in Python: def quick_sort(arr): if len(arr) <= 1: return arr else: pivot = arr[0] less_than_pivot = [x for x in arr[1:] if x <= pivot] greater_than_pivot = [x for x in arr[1:] if x > pivot] return...

For example, in a plain text file, the selection starts within the whole word then extends to the sentence, paragraph, and so on. In a Java file, if you start by selecting an argument in a method call, it will extend to all arguments, then to the whole method, then to the expressio...
and they become even more difficult to debug. For example, any young programmer can easily understand the selection sort and debug it when it does not work. But for the quick sort, it is a different story. The gain provided by a better algorithm does not always justify the effort to get...
