push(x) -- Push element x to the back of queue. pop() -- Removes the element from in front of queue. peek() -- Get the front element. empty() -- Return whether the queue is empty. Notes: You must use only standard operations of a stack -- which means only push to top, peek...
当输出栈outStack为空时,执行出队操作则需要先将输入栈inStack中的元素弹出并压入输出栈。详细的步骤如图2所示。 图2:将一个元素出队 代码(Java)实现如下。 /** Removes the element from in front of queue and returns that element. */publicintpop(){if(empty()) {thrownewIllegalArgumentException("[E...
Notes: You must useonlystandard operations of a stack -- which means onlypush to top,peek/pop from top,size, andisemptyoperations are valid. Depending on your language, stack may not be supported natively. You may simulate a stack by using a list or deque (double-ended queue), as long...
Implement the following operations of a queue using stacks. push(x) -- Push element x to the back of queue. pop() -- Removes the element from in front of queue. peek() -- Get the front element. empty() -- Return whether the queue is empty. Notes: You must use only standard oper...

Perhaps we should implement jstack differently. It could generate a partial javacore file to the console. We can decide which parts of the javacore to generate, and perhaps control different parts via stack options. This would give the same monitor info available in a javacore, and also inclu...
