What is the name used for the camera s view from a single position?

You are given a data set with information from 1,000 high school students (of which the following is a part of the data) and ask

serg [7]

Answer:

Classification

Explanation:

Building a machine learning solution that can predict the success of a student in completing a college degree is a binary problem. There are two possible answer: success or not success.

This brings us to a supervised machine learning problem, where one trains the technique with labeled data whether it is a success or not. Since the target variable is discrete (not continuous), classification technique has to be used.

A contiguous subsequence of a list S is a subsequence made up of consecutive elements of S. For example, if S is 5,15,-30,10,-5,

Sindrei [870]

Answer:

We made use of the dynamic programming method to solve a linear-time algorithm which is given below in the explanation section.

Explanation:

Solution

(1) By making use of the dynamic programming, we can solve the problem in linear time.

Now,

We consider a linear number of sub-problems, each of which can be solved using previously solved sub-problems in constant time, this giving a running time of O(n)

Let G[t] represent the sum of a maximum sum contiguous sub-sequence ending exactly at index t

Thus, given that:

G[t+1] = max{G[t] + A[t+1] ,A[t+1] } (for all 1<=t<= n-1)

Then,

G[0] = A[0].

Using the above recurrence relation, we can compute the sum of the optimal sub sequence for array A, which would just be the maximum over G[i] for 0 <= i<= n-1.

However, we are required to output the starting and ending indices of an optimal sub-sequence, we would use another array V where V[i] would store the starting index for a maximum sum contiguous sub sequence ending at index i.

Now the algorithm would be:

Create arrays G and V each of size n.

G[0] = A[0];

V[0] = 0;

max = G[0];

max_start = 0, max_end = 0;

For i going from 1 to n-1:

// We know that G[i] = max { G[i-1] + A[i], A[i] .

If ( G[i-1] > 0)

G[i] = G[i-1] + A[i];

V[i] = V[i-1];

Else

G[i] = A[i];

V[i] = i;

If ( G[i] > max)

max_start = V[i];

max_end = i;

max = G[i];

EndFor.

Output max_start and max_end.

The above algorithm takes O(n) time .

What led to fall of axum?

stiks02 [169]

The main factors that led to the fall of the Aksum in the seventh century were climate change and the obstruction of international trade routes around the Red Sea brought on by the growing supremacy of the Muslims in Ethiopia. Other contributing factors included a reduced crop yield due to excess cultivation of land, Persian interference and the rise of Christianity in the region.

Write a program with class name Digits that prompts the user to input a positive integer and then outputs the number reversed an

mr Goodwill [35]

Answer:

Written in Python:

inputnum = int(input("User Input: "))

outputnum = 0

total = 0

while(inputnum>0):

remainder = inputnum % 10

outputnum = (outputnum * 10) + remainder

inputnum = inputnum//10

total = total + remainder

print("Reverse: "+str(outputnum))

print("Total: "+str(total))

Explanation:

This prompts user for input

inputnum = int(input("User Input: "))

This initializes the reverse number to 0

outputnum = 0

This initializes total to 0; i.e. sum of each digit

total = 0

The following iteration gets the reverse of user input

while(inputnum>0):

remainder = inputnum % 10

outputnum = (outputnum * 10) + remainder

inputnum = inputnum//10

 This adds each digit of user input

total = total + remainder

This prints the reversed number

print("Reverse: "+str(outputnum))

This prints the sum of each digit

print("Total: "+str(total))

A corporate office has a huge number of employees. Every employee has a telephone next to their computer so that they can call o

Lemur [1.5K]

Answer:

PBX system.

Explanation:

PBX is an acronym for private branch exchange. It is a private telephone network service that allows users to communicate by making or taking inbound and outbound calls using a gateway, voice mail, transfer calls, call queues and recording.

In an office, employees having a PBX telephone can call other employees in the same office regarding official work.

The callers have to dial a particular extension number so that the intended receiver gets the call.

Example of an extension number is 111-5001 and 111-5002, with a central number as 111-5000.

Hence, the telephone network used in this office is the PBX system.
