WebAlthough there is no. of problems for Greedy algorithm in Array few of them are:-. Maximum and minimum product subset of an array. Maximise and minimise array sum after k-negotiations. Minimum increment/decrement to make array non-increasing. Sorting array with reverse around the middle. WebDec 11, 2010 · Since OOP using Composition naturally generates a graph of objects that's a good approach to use here. Graphs are essentially composed of 2 elements: Nodes and Edges. Start with a Node class. It has a color, an id, and an ArrayList of Edges. Edges form a relationship between 2 nodes, and may have a weight and a direction.

WebMathmatically, a proper vertex coloring of an undirected graph G= (V,E) is a map c: V -> S such that c (u) != c (v) whenever there exists an edge (u,v) in G. The elements of set S are called the available colors. The problem is often to determine the minimum cardinality (the number of colors) of S for a given graph G or to ask whether it is ...
