a tree that is created from another connected graph and that contains all of the connected graph's vertices, is connected, and contains no circuits is called a/an
Answers
A tree that is created from another connected graph and contains all of the graph's vertices, is connected and contains no cycles or circuits is called a spanning tree.
A spanning tree is a subset of a connected graph that includes all of its vertices while forming a tree-like structure. It is obtained by removing some edges from the original graph while maintaining connectivity and ensuring that no cycles or circuits are present. In other words, it connects all the vertices of the original graph without creating any loops or redundant paths.
Spanning trees have various applications in graph theory and network design. They provide a way to identify the essential connections within a graph while eliminating unnecessary edges. Spanning trees can be used to find the minimum-cost paths, determine network efficiency, and identify hierarchical structures. Algorithms like Prim's algorithm and Kruskal's algorithm are commonly used to find spanning trees by selecting the most optimal edges based on certain criteria, such as edge weights or priorities.

which expression fails to compute the area of a triangle having base b and height h (area is one-half base time height)? a. (1.0 / 2.0 ) * b * h b. (1 / 2) * b * h c. (b * h) / 2.0 d. 0.5 * b * h
Answers
The expression that fails to compute the area of a triangle having base band height h (the area is one-half base time height) will be;
(a) (1.0/2.0) bh.
Since triangle is a closed two-dimensional figure that has three sides. The area of a triangle can be computed by finding one-half of the product of its base and height.
A = (1/2) bh.
The formula for finding the area of a triangle can be expressed in various ways, that include:
area = 0.5bh,
area = (bh) / 2,
area = b * h / 2.
From the expressions, the option that fails to compute the area of a triangle having baseband height h is option (a) (1.0/2.0) * b * h. This is because 1.0/2.0 is equal to 0.5, and
Thus, the expression (1.0/2.0) bh is equivalent to 0.5bh, which is the correct formula for finding the area of a triangle.
Option (a) (1.0/2.0) * b * h fails to compute the area of a triangle having base band height h .

The third process when starting a computer is the boot process. It initializes the hardware and loads the operating system into memory.
When starting a computer, the third process in the startup sequence is the boot process. This process is responsible for initializing the computer's hardware and loading the operating system into memory.
The boot process consists of several steps:
Power-on self-test (POST): The computer performs a self-check to ensure that all hardware components are functioning correctly. This includes checking the processor, memory, and other essential components.Loading the BIOS: The BIOS (Basic Input/Output System) is a firmware that manages the computer's hardware. It is responsible for initializing the hardware and preparing the system for booting.Initiating the operating system: Once the BIOS completes its tasks, it hands over control to the operating system. The operating system takes over and allows the user to interact with the computer.The boot process is crucial for the computer to start up successfully and for the user to access the operating system and its functionalities.

blueprint could not be loaded because it derives from an invalid class. check to make sure the parent class for this blueprint hasn't been removed! do you want to continue (it can crash the editor)?
Answers
The error message, "Blueprint could not be loaded because it derives from an invalid class" implies that the blueprint could not be loaded due to the fact that it is based on an invalid class. This error message can occur when a blueprint's parent class has been deleted or is no longer present in the game.
Thus, the blueprint cannot be loaded by the game engine. The message goes further to ask the user to ensure that the parent class has not been removed before continuing. If the user chooses to continue, the engine may crash. This can happen if the engine is not able to identify the base class of the blueprint and thus, cannot load the blueprint's content. If you encounter this issue, it is advisable to try to locate and restore the parent class for the blueprint in order to fix the error. One of the ways to do this is to restore the base class that was removed or to rebuild the parent class.
It is important to note that if the blueprint is critical to the game, a crash may result if the blueprint is loaded without fixing the error. In conclusion, Blueprint could not be loaded because it derives from an invalid class can be fixed by restoring the parent class or rebuilding it to ensure that the game engine can load the blueprint without crashing.

Write a function path that returns the path from the root of the tree to the given entry value if it exists and [] if it does not. You can assume all entries are unique.
Answers
To implement this function, you can start by creating a recursive function that takes in the current node, the target value, and the current path.
To write a function path that returns the path from the root of the tree to the given entry value if it exists and [] if it does not, you will need to perform a depth-first search of the tree until you find the target value.
As you traverse the tree, keep track of the path you have taken so far. If you find the target value, return the path you have taken to get there. If you reach the end of the tree without finding the target value, return an empty list.
If the current node is None, return an empty list. If the current node's value is the target value, return the current path. If the target value is not found, call the function recursively on the current node's children, passing in the updated path.
Finally, call this function on the root node with an empty path to begin the search.

Design a minimal set of test cases for the function simple() . Your test suite must meet the loop boundary adequacy criterion and branch coverage criterion (note: give test cases rather than test case specifications). Which of the two criteria subsume the other? Explain your answer.

Answers
A minimal set of test cases for the function simple() that meet the loop boundary adequacy criterion and branch coverage criterion are as follows:
Loop Boundary Adequacy Criterion: In order to satisfy the loop boundary adequacy criterion, the test cases must exercise each of the following conditions at least once: Test case #1: (c+d)<=a+bTest case #2: (c+d)>a+b and the loop never executes Test case #3: (c+d)>a+b and the loop executes exactly once Branch Coverage Criterion: In order to satisfy the branch coverage criterion, the test cases must exercise each of the following paths at least once:Test case #1: i=b+a, j=d, k=k+5Test case #2: i=b+a, j=d, k=k+5, i=i+2, j=i+c-d+a Test case #3: i=b+a, j=d, k=k+5, i=i+2, j=i+c-d+a, j>i+5, k=j+i Subsumption of the criteria: Loop boundary adequacy criterion subsumes the branch coverage criterion. This is because loop boundary adequacy criterion requires that every branch in the code is executed at least once which includes the branches that are covered in the branch coverage criterion. Therefore, we can say that loop boundary adequacy criterion subsumes the branch coverage criterion.
