Graphs are non-linear data structures consisting of vertices (nodes) and edges that connect them. Formally denoted as $G = (V, E)$, where $V$ represents the set of vertices and $E$ represents the set of edges, graphs are widely utilized to model relationships in computer networks, logistics, and soc...
Problem Description We need to implement a stack that starts empty and supports four core operations: push x – Insert the number x at the top of the stack; pop – Remove the element from the top of the stack; empty – Check if the stack is empty; output "YES" if it is, otherwise "NO&quo...
232. Implementing Queue Using Stacks Implement a queue using stacks with the following operations: push(x) -- Insert an element at the back of the queue. pop() -- Remove and return the element from the front of the queue. peek() -- Return the element at the front of the queue without removing it. em...
Understanding Stack and Queue Implementations In C++, both stacks and queues are container adapters, typically built upon underlying containers like vector or deque. Their core concepts are Last-In-First-Out (LIFO) and First-In-First-Out (FIFO), respectively. 232. Implement Queue using Stacks Design...

Data structures organize and store data in specific arrangements defining the relationships between elements. Linear structures establish a one-to-one sequential relationship among elements, encompassing arrays, linked lists, stacks, and queues. Arrays An array allocates a contiguous block of memory...
Introduction to Heaps A heap is a specialized tree-based data structure that satisfies strict ordering properties. Conceptually, it represents a complete binary tree, but physically it is stored sequentially within a one-dimensional array. In a min-heap, every parent node's value is less than or equ...
Return Statement Behavior A return statement may contain a numeric value or an expression. Expressions are evaluated before returning: int sum(int x, int y) { return x + y; } // Usage example switch (op) { case 1: scanf("%d %d", &a, &b); result = sum(a, b); printf("Result: %d\...
The underlying key-value mapping utilizes an array of linked lists. The primary container manages two separate hash tables (buckets[2]) to facilitate online resizing. The buckets[0] slot holds the active data, while buckets[1] is allocated exclusively for progressive migration. Additional fields tra...
Core Operations Priority queues are specialized ordered collections where the element with highest assigned priority is always positioned at the front of the sequence. The C++ Standard Library's priority_queue container adapter supports the following core operations: push(value): Inserts a new eleme...
