Answer:
- Iterate over the Bellman-Ford algorithm n-1 time while tracking the parent vertex and store in an array.
- Do another iteration and if no relaxation of the edges occurs in the nth iteration then print of return "There are no negative cycle".
- Else, store the vertex of the relaxed edge at the nth iteration with a variable name.
- Then iterate over the vertexes starting from the store vertex until a cycle is found then print it out as the cycle of negative weight.
Explanation:
The Bellman-Ford algorithm can be used to detect a negative cycle in a graph. The program should iterate over the algorithm, in search of a relaxed edge. If any, the vertex of the specified edge is used as a starting point to get the target negative cycle.
Suppose that a t-shirt comes in five sizes: S, M, L, XL, XXL. Each size comes in four colors. How many possible t-shirts are there?
Answer:
120
Explanation:
This question is basically asking how many ways can we arrange 5 sizes of shirts if they come in 4 colors.
5 permutation of 4
To find permutation, we use the formula
P(n, r) = n! / (n - r)!
Where
n is the size of the shirts available, 5
r is the color of each shirt available, 4
P(5, 4) = 5! / (5 - 4)!
P(5, 4) = (5 * 4 * 3 * 2 * 1) / 1!
P(5, 4) = 120 / 1
P(5, 4) = 120
Therefore, the total number of shirts available is 120
Relatively simple CRUD (create, read, update, delete) web applications development can be facilitated with: _________.
a. HTTP
b. HTTPS
c. Web Application Frameworks
d. Cascading Style Sheets (CSS)
e. Document Object Model (DOM)
Answer:
c. Web Application Frameworks
Explanation:
Web Application Frameworks is a form of a software framework that is made to perform support for the building of web applications such as web services, web resources, and web APIs. Web frameworks.
Also, Web Application Frameworks automatically perform the function of primary activities carried out in web development such as create, read, update, delete.
Hence, in this case, the correct answer is Web Application Framework.

Assume the clock for a 4-bit binary counter is 80 kHz. The output frequency of the fourth stage (Q3) is
Answer:
5kHz
Explanation:
There are four stages so N = 2⁴ = 16.
The frequency at nth stage is given by
[tex]f_n = \frac{f_{clk}}{N} = \frac{80kHz}{16} = 5kHz[/tex]
The output frequency of the fourth stage (Q3) is 5kHz. Thus the correct option is A.
What is a 4-bit binary counter?On each clock cycle, the 4-bit synchronous counter successively counts up from 0 (0000) to 15 as outputs ( 1111 ). It is also known as a 4-bit Synchronous Up Counter as result.
We required four Flip Flops to create a 4-bit counter, as indicated by the number 4 Flip Flops. The counter also has a reset pin, which enables it to enter an all-zero mode in which its output is "0."
The Q output of the previous flip-flop triggers the CLK input in the 4-bit counter above, as opposed to the Q output as in the up counter configuration, where the output of each flip-flop changes state on the rising edge.
There are four stages so N = 2⁴ = 16.
The 4-bit binary counter is 80 kHz.
In order to calculate the output frequency the 4-bit binary counter is divided by 16 which is equal to 5kHz.
Therefore, option A is appropriate.

g A CPU is equipped with a cache; Accessing a word takes 20 clock cycles if the data is not in the cache and 5 clock cycles if the data is in the cache. What is the effective memory access time in clock cycles if the hit ratio is 90%
Answer:
6.5
Explanation:
The formula to calculate the efficiency is;
= (cache-click-cycle x hit ratio) + ( memory-clock-cycle x 1 - hit ratio)
= (5 x 0.9) + ( 20 x 0.1)
= 4.5 + 2
= 6.5
In this exercise we have to use the knowledge of efficiency, in this way, using the data already informed, we can say that the result of this is:
6.5 effective memory
In this exercise, it was informed that some conditions must be established, that is:
Hit radio: 90%Memory: 20Cache: 5
The formula to calculate the efficiency is;
[tex]efficiency= ((cache-click-cycle)(hit \ ratio)) + ( (memory-clock-cycle)(1 - hit \ ratio))[/tex]
Substituting the known values in the formula above, we find that:
[tex]= (5)(0.9) + ( 20)(0.1)\\= 4.5 + 2\\= 6.5[/tex]

Which important aspect of the Roman Empire did the barbarians destroy?
Answer:
centers of learning
Explanation:
Under the leadership of Emperor Valens, Rome was already having financial hardships. This meant that it didn't have enough money left to repair its empire nor to strengthen it against invaders. Soon, the barbarians such as the Franks, Huns, Saxons, etc. started attacking Rome. They spent a lot of time destroying the outer regions of the empire because they were also at war with each other. They penetrated Rome and it soon fell. The barbarians didn't only destroy the cities but they also destroyed the "centers of learning." Roman people were known to value education. With the fall of the Roman Empire, so did education and sophisticated architectures follow.

g Assume that this program is run on a processor with data cache of size big enough that the entire array arr can fit in the cache. (a) How many paths does the function foo of this program have
Answer:
A. 2
Explanation:
The food function in the C source code uses two for loop statements to fill and array of size 100 with 100 values ranging from 1 to 100 and the second to get the total sum to the values in the array. With this, two program paths are created.
