Expert Solution & Answer
Chapter 17, Problem 1TC
Explanation of Solution
Given:
A password for a system is PINE963$&apple, which is not a strong password.
To find:Â The reason why PINE963$&apple cannot be treated as a strong password.
Solution:
PINE963$&apple is not a strong password because this password contains words that can be easily guessed by an attacker.
A strong password contains at least 16 characters.
The password should not contain words that can be found in a dictionary. The password: PINE963$&apple, has two dictionary words PINE and apple.
A strong password contains a combination of uppercases and lowercases letters, numbers, and symbols.
A strong password does not use adjacent keys present on the keyboard.

For the CSMA protocol (without collision detection), indicate which packets are successfully
transmitted. You should assume that it takes .2 time units for a signal to propagate from one node to
each of the other nodes. You can assume that if a packet experiences a collision or senses the
channel busy, then that node will not attempt a retransmission of that packet until sometime after
t=5. Hint: consider propagation times carefully here. (Note: You can find more examples of problems similar to this here B.]

Just wanted to know, if you had a scene graph, how do you get multiple components from a specific scene node within a scene graph? Like if I wanted to get a component from wheel from the scene graph, does that require traversing still?
Like if a physics component requires a transform component and these two component are part of the same scene node. How does the physics component knows how to get the scene object's transform it is attached to, this being in a scene graph?

For simplification, only consider cutting the rope at an integer position by the meter metric. Each cut has a cost associated with it, c(m), which is the cost of cutting the rope at position m. (You can call c(m) at any time to return the cost value.) The goal is to cut the rope into k smaller pieces, minimizing the total cost of cutting. B Provide the pseudo-code of your dynamic programming algorithm f(n,k) that will return the minimum cost of cutting the rope of length n into k pieces. Briefly explain your algorithm.
