Here is a C++ Program to Perform Greedy ColoringAlgorithm:Begin    Take the number of vertices and edges as input.    Create function greedyColoring() to assign color to vertices:    A) Assign the first color to first vertex.    B) Initialize the remaining vertices.    C) Declare a temporary array to store the available colors.    D) Assign color to the remaining vertices.    Print the solution. EndExample Code#include #include using namespace std; int n,e,i,j; vector g; vector col; bool visit[1001]; void greedyColoring() {    col[0] = 0;    for (i=1;i

To add a value to the Quartet Tuple, use the addAtX() method. The index can be set here with the X i.e. the place where the value gets added.Let us first see what we need to work with JavaTuples. To work with Quartet class in JavaTuples, you need to import the following package −import org.javatuples.Quartet;We will use Quintet class; therefore, we will import the following package −import org.javatuples.Quintet;Note − Steps to download and run JavaTuples program If you are using Eclipse IDE to run Quartet Class in JavaTuples, then Right Click Project → Properties → Java Build Path → Add ...

Here we will see what are the differences between int and const_int& in C or C++.The int is basically the type of integer type data. And const is used to make something constant. If there is int& constant, then it indicates that this will hold the reference of some int type data. This reference value is constant itself. So the const is redundant. The compiler may return warning or some error.The const int& is same as int const&. So this refers to a constant integer. The integer cannot be modified through the reference.

This is a C++ Program to implement Network_Flow problem using Ford Fulkerson algorithm.Algorithms:Begin    function bfs() returns true if there is path from source s to sink t in    the residual graph which indicates additional possible flow in the graph. End Begin    function fordfulkarson() return maximum flow in given graph:    A) initiate flow as 0.    B) If there is an augmenting path from source to sink, add the path to flow.    C) Return flow. EndExample Code#include #include #include #include #define n 7 using namespace std; bool bfs(int g[n][n], int s, int ...

What do the id and scope attribute mean in the action elements in JSP?

Ankith Reddy

Updated on 30-Jul-2019 525 Views

These are two attributes that are common to all Action elements: the id attribute and the scope attribute.Id attributeThe id attribute uniquely identifies the Action element and allows the action to be referenced inside the JSP page. If the Action creates an instance of an object, the id value can be used to reference it through the implicit object PageContext.Scope attributeThis attribute identifies the lifecycle of the Action element. The id attribute and the scope attribute are directly related, as the scope attribute determines the lifespan of the object associated with the id. The scope attribute has four possible values:(a) ...
