quescol A stack is a Linear Abstract Data Type (ADT) that follows the LIFO(Last in first out) property. There are two operation which can be performed on stack 1). PUSH 2). POP 1). PUSH operation of Stack PUSH operation of the stack is used to add an item to a stack at the top. We can … Read more
Java Program to implement stack using linked list Output
A stack is a fundamental data structure that follows the Last In, First Out (LIFO) principle, meaning the last element added to the stack will be the first one to be removed. It’s like a stack of plates, you add to the top and take from the top. This post will explore how to implement … Read more
Stack can be implemented by both array and linked list. There is some limitation or you can say that drawback in stack implementation using an array is that the array must be declared with some fixed size. In case if the size of the array becomes small to perform the required operation so this is … Read more
A stack is a linear data structure in which the elements are added and removed only from one end, which is called the TOP. Hence, a stack is also called a LIFO (Last-In-First-Out) or FILO(First In Last Out) data structure, which means the element that was inserted last is the first one to be taken … Read more
Dijkstra’s algorithm, given by a brilliant Dutch computer scientist and software engineer Dr. Edsger Dijkstra in 1959. Dijkstra’s algorithm is a greedy algorithm that solves the single-source shortest path problem for a directed and undirected graph that has non-negative edge weight. For Graph G = (V, E)w (u, v) ≥ 0 for each edge (u, … Read more
What is Spanning Tree? A spanning tree of a graph G is a subgraph of G that is a tree that includes all of the vertices of G and a minimum number of edges. A spanning tree does not contain any cycles and all the vertices should be connected. For every connected and undirected graph … Read more
Breadth-first search graph traversal techniques use a queue data structure as an auxiliary data structure to store nodes for further processing. The size of the queue will be the maximum total number of vertices in the graph. It is a smart way to look through data organized in a graph. A graph is a collection … Read more
Hashing is an approach to convert a larger key into a smaller integer value within a given limited range. Here the key is a larger value that we need to store And the integer value is an address in the hash table where the key will be store. To find integer address from key-value we … Read more
