A root of a dag is a vertex r such that every vertex of the dag can be reached by a directed path from r. Write pseudocode to determine whether a dag is rooted. Consider the following algorithm to check connectivity of a graph defined by its adjac...

A digital circuit is a circuit where the signal must be high or low or we can say in boolean terms. Digital gates are commonly made from a small circuit called logic gates. Each logic gates performs a specific task. Answer and Explanation:1 ...
