1. Array Stack Extended Challenges Write a C program to implement a stack using an array with push and pop operations. Sample Solution: C Code: #include<stdio.h>#defineMAX_SIZE100// Maximum size of the stackintstack[MAX_SIZE];// Array to implement the stackinttop=-1;// Variable to ...
C language program to implement stack using array #include<stdio.h>#defineMAX 5inttop=-1;intstack_arr[MAX];/*Begin of push*/voidpush(){intpushed_item;if(top==(MAX-1))printf("Stack Overflow\n");else{printf("Enter the item to be pushed in stack :");scanf("%d",&pushed_item);top...
If the Linked List is already empty then do nothing. Output that empty stack. If the Linked List is not empty then delete the node from head. C++ implementation #include<bits/stdc++.h>usingnamespacestd;structnode{intdata;node*next;};//Create a new nodestructnode*create_node(intx){struct...

// 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 ...
【LeetCode题解】232_用栈实现队列(Implement-Queue-using-Stacks) 目录 描述 解法一:在一个栈中维持所有元素的出队顺序 思路 入队(push) 出队(pop) 查看队首(peek) 是否为空(empty) Java 实现 Python 实现 解法二:一个栈入,一个栈出 思路 入队(push) 出队(pop) 查看队首(peek) 是否为空(empty) ...
In order to make end user independent from implementation details of the stack implementation whether it is implemented using linked list or array, we define an interface Stack as follows. The following Stack interface can be assigned any object that implements this interface no matter the ...
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 the MyStack class: void push(int x) Pushes element x to the top of the stack. int pop() Removes the el...
class Stack { public: // Push element x onto stack. void push(int x) { if(q1.empty()&&q2.empty()) q1.push(x); else if(!q1.empty()) q1.push(x); else q2.push(x); } // Removes the element on top of the stack. void pop() { if(!q1.empty()) { while(q1.size()!=1...
4. In the function delete(), firstly check if the queue is empty. If it is, then print the output as “Queue Underflow”. Otherwise print the first element of the array queue_array[] and decrement the variable front by 1. 5. In the function display(), using for loop print all the...
