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 useonlystandard operatio...
Can you solve this real interview question? Implement Stack using Queues - Implement a last-in-first-out (LIFO) stack using only two queues. The implemented stack should support all the functions of a normal stack (push, top, pop, and empty). Implement
Use one stack for pushing element, the other stack for poping element. When peek/pop an elements, if the output stack is empty, shift all elements from input stack to output stack first. Code class MyQueue { Stack<Integer>in; Stack<Integer>out; /** Initialize your data structure here. ...
class MyQueue: def __init__(self): self.stack_in = [] self.stack_out = [] def push(self, x: int) -> None: self.stack_in.append(x) def pop(self) -> int: if self.empty(): return None if self.stack_out: return self.stack_out.pop() ...
// Removes an element from the queue pop(st) Dequeue an element from the queue. C++ Java Python #include<bits/stdc++.h> using namespace std; class Stack { queue<int>q; public: void push(int val); void pop(); int top(); bool empty(); }; void Stack::push(int val) { int ...
/** Push element x to the back of queue. */publicvoidpush(intx) {s1.push(x); } So what if usingpeekto get the front element of the queue at this time? Logically speaking, the front element should be 1, but ins1, 1 is pushed to the bottom of the stack. Now ...
