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 ...
}/** Returns whether the queue is empty. */publicbooleanempty(){returnstackIn.isEmpty() && stackOut.isEmpty(); }// 如果stackOut为空,那么将stackIn中的元素全部放到stackOut中privatevoiddumpstackIn(){if(!stackOut.isEmpty())return;while(!stackIn.isEmpty()){ stackOut.push(stackIn.pop());...

Queue in C is a data structure that is not like stack and one can relate the behavior of queue in real -life. Unlike stack which is opened from one end and closed at the other end which means one can enter the elements from one end only. Therefore, to overcome the scenario where we...
