What supporting data structure is used for traversing a graph based on the breadth-first traversal technique?

Depth-first traversal is equivalent to which of the following traversal of trees?

An approach to problem-solving in which different sequences are considered until the best suitable solution is found is called

If visitedNodes = [A], what is the value of visitedNodes in the next step?

If node C has been visited in the current step, what is the value of visitedNodes?

Select All That Apply.

If node D is visited in the current step, what is the value of the supporting data structure?

Node A is visited in the current step and nodelist = [A]. What is the value of supporting data structure in the next step?

Node D is added to the list of nodelist in the current step. Assuming that D’s neighbours are also added, what is the value of supporting data structure?

What is the order of nodes visited for depth-first traversal of this tree?

When a program theoretically can be solved, but if they take potentially millions of years to physically solve, they are classed as _______.

When a problem can be solved with an algorithm which has a polynomial time complexity or better (eg, O(n), O(n^2), O(n^k) ).

When a problem does not have a polynomial time solution – may have a theoretical solution but would be impossible to solve the problem within a reasonable time frame (eg, O(2^n), O(n!) ).

A problem is defined as being ________ if there is an algorithm that can solve every instance of it in a finite number of steps.
