Undirected Grаphs Prоgrаmming We sаy that a graph is 2-cоlоrable if there is a way to label each node with a color in such a way that no node is adjacent to another of the same color. That is, the colors alternate. Implement a method to check if an undirected graph is 2-colorable and generate labels for the graph; use the method signature below. Your answer should maintain an array called color that stores the color of each vertex as it processes the graph. If it is successful, the contents of the array will be a coloring of the graph. Assume that you are using the standard Graph ADT discussed in class, have the following globals (marked, colors) already available, and the graph is connected. Do not import any packages. enum Color {RED, GREEN, UNLABELED;} boolean[] marked = new boolean[G.V()]; Color[] colors = new Color[G.V()]; bool isTwoColorable(Graph G) { //assume every index in colors is set to UNLABELED initally. //start algorithm by beginning at node 0 and coloring it RED if(isTwoColorable(G, RED, 0)) return colors;//returns the coloring of the nodes if the graph is two colorable else; return null; //indicates graph is not two colorable } boolean isTwoColorable(Graph G, Color c, int v) { //TODO: IMPLEMENT ME.
Prоgrаmming Implement а Jаva methоd called mergeStacks (signature given belоw) that takes two sorted stacks in as arguments, and produces a new sorted stack created from merging the contents of both into the sorted order. Both the input stacks and merged result will have the smallest element at the top. Example: Let s1 = (top) [1, 2, 3, 8] and s2 = (top) [4, 5, 6, 7], which produces result = (top) [1, 2, 3, 4, 5, 6, 7, 8]. Brackets here are showing the contents of the stacks at a high-level - with top as a label on one side - they do not indicate arrays. If needed, emptying the input stacks is fine. Assume that the Stack class has the typical default constructor, a pop(), a push(), a peek(), an isEmpty(), and size() methods. This stack supports automatic resize and pop() throws an Exception if performed on an empty stack. Also assume that the method “boolean less(Comparable v, Comparable w)” which returns true if v is less than w is available. Creating additional helper methods is fine but you should provide a one line comment that indicates their purpose. You may not import any packages. (Hint: be careful with the ordering!) public Stack mergeStacks(Stack s1, Stack s2) { //TODO!
