Chapter 8, Problem 6AW

Program Plan Intro

Decision structure:

Sequence structure cannot handle all types of tasks. These can be achieved using the decision structure. Example: “if” statement.

“if” statement:

The “if” statement is used to create a decision structure; it allows more than one execution path for program. If Boolean expression is true, the “if” statement causes one or more statements to be executed.

Indentation in the “if” statement:

While using the “if” statement, the following indentations should be followed:

• The block of statements that follow the “if” statement should be indented.

• The Python interpreter uses this to check where the block begins and ends.

Algorithm:

Algorithm to replace character‘t’ with its upper case version is as follows:

• Iterate through the string using the “for” loop.

• Using the “if” statement, check whether character is‘t’.

• If character is “t”, convert to upper case.

• Create a new string with the upper case “t” character using the concatenation operation.

• Display a new string.

6.3A-3. Multiple Access protocols (3). Consider the figure below, which shows the arrival of 6 messages for transmission at different multiple access wireless nodes at times t=0.1, 1.4, 1.8, 3.2, 3.3, 4.1. Each transmission requires exactly one time unit. 1 t=0.0 2 3 45 t=1.0 t-2.0 t-3.0 6 t=4.0 t-5.0 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.] ☐ U ப 5 - 3 1 4 6 2

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?
