The code gets execute slower when the eval() method is used. It also has security implementations since it has a different scope of execution.ExampleHere’s how you can ... Read More
To make an anchor tag refer to nothing, use “javascript: void(0)”. The following link does nothing because the expression "0" has no effect in JavaScript. Here the expression "0" is evaluated, but it is not loaded back into the current document.ExampleLive Demo Click the following, This won't react at all... Click me!

Graph coloring problem is a special case of graph labeling. In this problem, each node is colored into some colors. But coloring has some constraints. We cannot use the same color for any adjacent vertices.For solving this problem, we need to use the greedy algorithm, but it does not guaranty to use minimum color.Input and OutputInput: Adjacency matrix of the graph. 0 0 1 0 1 0 0 1 1 1 1 1 0 1 0 0 1 1 0 1 1 1 0 1 0 Output: Node: 0, Assigned with Color: 0 Node: 1, Assigned with Color: 0 ...

Fleury’s Algorithm is used to display the Euler path or Euler circuit from a given graph. In this algorithm, starting from one edge, it tries to move other adjacent vertices by removing the previous vertices. Using this trick, the graph becomes simpler in each step to find the Euler path or circuit.We have to check some rules to get the path or circuit −The graph must be a Euler Graph.When there are two edges, one is bridge, another one is non-bridge, we have to choose non-bridge at first.Choosing of starting vertex is also tricky, we cannot use any vertex as ...
