Edge coloring is a method of coloring the edges of a graph, such that no two edges having a common vertex is colored with same color. A line Graph is a special type of graph which help us to assume an edge-coloring problem into a vertex-coloring problem. In other words, ... Read More

Graph coloring is a technique in which, we assign colors to the vertices of a graph such that no two adjacent vertices have same color. Bipartite graph a special kind of graph which is possible to color by just two colors. In this article, we will discuss how to perform ... Read More

In C++, segmentation fault is a runtime error that occur when your program attempts to access an area of memory that it is not allowed to access. In other words, segmentation fault occur when your program tries to access memory that is beyond the limits that the operating system allocated ... Read More

The C++ functions can receive objects in multiple ways, depending upon how you want the function to interact with the object. You can either define functions that can modify the original objects or define functions that will make a copy of original object and modify the copy without affecting ... Read More

A subsequence is a sequence that can be derived from another sequence by deleting some elements and without changing the order of elements in sequence. For example, the sequences [3, 10], [3, 2, 20] and [3, 10, 20] are some of the subsequences of [3, 10, 2, 1, 20]. ... Read More
