Including a vertex within the contagiousness network representation of a chart means expanding the measure of the network by one push and one column. The unused push and column speak to the associations of the recently included vertex with the existing vertices. Additionally, expelling a vertex requires evacuating its comparing push and column from the contagiousness lattice, subsequently altering the measure of the network in like manner. Including a vertex includes adding a push and column with beginning values of 0, whereas evacuating a vertex includes erasing the comparing push and column, viably decreasing the measure of the lattice.

Adjacency lists effectively store graph relationships. Graph algorithms and operations use it. Adding and deleting edges can dynamically change the connections between vertices. Graph modification, connection analysis, and evolution need this procedure.Adding and deleting edges link and detach vertices, respectively. The adjacency list representation commonly performs these actions by altering the vertices' adjacency lists. Using a vector of vectors, sets, or maps of sets may change the implementation.New edges create pathways and linkages in the graph. However, removing edges breaks connections, changing graph structure and dynamics. These procedures are essential for graph adjacency list integrity and evolution. Methods Used ... Read More

A binary tree is a data structure in which each node can have two children (at most). These children are known as left and right child respectively. Suppose we are given a parent array representation using which you have to a create a binary tree. The binary tree may have several isosceles triangles. We have to find the total number of possible isosceles triangles in that binary tree. In this article, we will explore several techniques in C++ to solve this problem. Understanding the Problem You are given a parent array. You have to represent it in the form ... Read More

A full binary tree is a special type of binary tree in which all the parent nodes either have two or no children. In data structures, these kinds of trees are considered as balanced and organized representation. Full binary trees may have a unique feature where each of the parent node is a product of its children. In this article, we will discuss about different methods for counting the number of full binary trees such that each node is product of its children using C++. Input Output Scenarios For example, in the array {1, 5, 3, 4}, we have ... Read More

Imagine a prisoner (or thief) wants to escape from a jail. In order to do so, he needs to cross N number of walls of varying lengths. He can climb X feet for each jump. But, since the walls are slippery, he falls down by Y feet after each jump. So, we need to calculate number of jumps required to cross all the walls. In this article, we will explore different C++ techniques to find the number of jumps required to escape the jail. Input Output Scenarios We have different heights of the N walls in the form of ...

In this article, we will discuss the possible solution of an exciting analytical question of how many jumps are required to reach a point (d, 0) from the origin in a 2D plane where you have been specified fixed length of jumps. We will use the fixed length of jumps and the target coordinates to find the minimum number of jumps required. Input Output Scenarios Suppose jump length can be a or b while the target point is (d, 0). Then, the given output is the minimum number of jumps required to reach target. Input: a = 7, b ...

Suppose you are given three different points (or coordinates) and you want to find out number of horizontal or vertical line segments which can be made by connecting those three points. Such line segments together are also known as polyline. You need concepts of computational geometry in order to solve this problem. In this article, we will discuss various approaches in C++ to tackle this problem. Input Output Scenarios Suppose c1, c2 and c3 are coordinates of 3 points in a cartesian plane. The number of horizontal or vertical line segments to connect these 3 points will be given as ... Read More
