Push Swap A program that sorts numbers using two stacks and a limited set of operations. Overview Push Swap is a program that takes a list of numbers as input and sorts them using two stacks (A and B) with a specific set of allowed operations. The goal is to sort the numbers in asce...
执行Push()的线程,会先构造数据项,并设置head_。执行Pop()的线程,会先加载head_,再做“比较/交换”操作,并增加引用计数,读取对应的Node节点,获取next的指向值。next的值是非原子对象,所以为了保证读取安全,必须确定存储(推送线程)和加载(弹出线程)的先行(happens-before)关系。因为原子操作就是Push()函数中的comp...
and then decreasing the top index by one. if it's implemented as a linked list, it involves returning the value of the head node and then moving the head pointer to the next node. in either case, the size of the stack decreases by one. how does the push operation work in a stack?

the push operation adds an element to the top of the stack. if the stack is implemented as an array, this involves adding an element at the next free index. if it's implemented as a linked list, it involves creating a new node and adjusting the pointers. in either case, the size of...
