A queue can be implanted using stack also. We need two stacks for implementation. The basic idea behind the implementation is to implement the queue operations (enqueue, dequeue) with stack operations (push, pop). Implementation: Let s1 and s2 be the two stacks used for implanting the queue...
Stack<Integer> aux =newStack<>(); publicvoidpush(intx) { while(!stack.isEmpty()){ aux.push(stack.pop()); } stack.push(x); while(!aux.isEmpty()){ stack.push(aux.pop()); } } // Removes the element from in front of queue. publicvoidpop() { stack.pop(); } // Get the ...

1. Which data structures can be used for queue implementation? An array, stack, or linked list can be used to implement a queue. Using an Array is the simplest way to implement a queue. 2. Which operation is used in the queue implementation? A queue is an object used to manipulate an...

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,其他线程必…
