深入解析c++无锁数据结构:无锁栈(lock-free stack)与无锁队列(lock-free queue) linux 10 人赞同了该文章 无锁栈(lock-free stack) 无锁数据结构意味着线程可以并发地访问数据结构而不出错。例如,一个无锁栈能同时允许一个线程压入数据,另一个线程弹出数据。不仅如此,当调度器中途挂起其中一个访问线程时,其...

Another important aspect to consider when dealing with the queue stack problem is the time and space complexity of the implemented solution. It is crucial to analyze the efficiency of the implementation in terms of the time taken to perform enqueue and dequeue operations, as well as the space ...
and a queue (fifo). what is a stack pointer? a stack pointer is a type of pointer used to keep track of the top of the stack. it points to the place in memory where the top element of the stack is stored. when an element is pushed onto the stack, the stack pointer is ...
For the array-based implementation of a stack, the push and pop operations take constant time, i.e. O(1). Applications of Stack Data Structure Although stack is a simple data structure to implement, it is very powerful. The most common uses of a stack are: To reverse a word - Put al...
