university | The class based version of discordeno

I have some column names that include two question marks at different spaces e.g. 'how old were you? when you started university?' - i need to identify which columns have two question marks in. any tips welcome! thanks

data

I would greatly appreciate any feedback you might offer regarding the issue I am having with my Word Prediction Shiny APP Code for the JHU Capstone Project.

My UI code runs correctly and displays the APP. (see image and code below)

Challenge/Issue: My problem is that after entering text into the "Text input" box of the APP, my server.R code does not return the predicted results.

Prediction Function:

When I run this line of code in the RConsole -- predict(corpus_train,"case of") -- the following results are returned: 1 "the" "a" "beer"

When I use this same line of code in my server.r Code, I do not get prediction results.

Any insight suggestions and help would be greatly appreciated.

This was a problem on Pramp. The question:

The awards committee of your alma mater (i.e. your college/university) asked for your assistance with a budget allocation problem they’re facing. Originally, the committee planned to give N research grants this year. However, due to spending cutbacks, the budget was reduced to newBudget dollars and now they need to reallocate the grants. The committee made a decision that they’d like to impact as few grant recipients as possible by applying a maximum cap on all grants. Every grant initially planned to be higher than cap will now be exactly cap dollars. Grants less or equal to cap, obviously, won’t be impacted.

Given an array grantsArray of the original grants and the reduced budget newBudget, write a function findGrantsCap that finds in the most efficient manner a cap such that the least number of recipients is impacted and that the new budget constraint is met (i.e. sum of the N reallocated grants equals to newBudget).

Analyze the time and space complexities of your solution.

This is what my solution looks like, in PHP.

I am working on getting some data, and as I am getting this data in a list, I want to write it into a csv file (maybe using pandas)

The data I want to convert is in the form of list:

I am really new to C and in my first half year at university. This is my first questio on StackOverflow.

My task is to program it so every string stored in numbers is being converted into a decimal, without changing anything outside the main function.

I am now trying for the past 4 hours to solve this problem, where I want to iterate trough every char in the string I am currently to then, based on there position in comparison to the length to convert it into a decimal.

My only question here is to someone help me to understand how I can get the string length without using strlen() due to the fact I can't add #include

This is what I got so far (getting the length of the array to iterate through every index):

I'm learning C programming in university, and for a quiz the question above came. I would like to understand how it will execute. Does it have something to do with the order of precedence?

I have course for Haskell programming at my university. And I must implement my own datatype "Stream" and its some functional:

I define a controller which code like bellow :

I have 3 remote computers (servers):

• computer 1 has internal IP: 10.1.7.245
• computer 2 has internal IP: 10.1.7.246
• computer 3 has internal IP: 10.1.7.247

(The 3 computers above are in the same network, these 3 computers are all using Ubuntu 18.04.5 LTS Operating System)

(My personal laptop is in another different network, my laptop also uses Ubuntu 18.04.5 LTS Operating System)

I use my personal laptop to connect to the 3 remote computers using SSH protocol and using user root : (Below ABC is a name)

• computer 1: ssh root@ABC.University.edu.vn -p 12001
• computer 2: ssh root@ABC.University.edu.vn -p 12002
• computer 3: ssh root@ABC.University.edu.vn -p 12003

I have successfully set up a Hadoop Cluster which contains 3 above computer:

• computer 1 is the Hadoop Master
• computer 2 is the Hadoop Slave 1
• computer 3 is the Hadoop Slave 2

======================================================

I starts HDFS of the Hadoop Cluster by using the below command on Computer 1: start-dfs.sh

Everything is successful:

• computer 1 (the Master) is running the NameNode
• computer 2 (the Slave 1) is running the DataNode
• computer 3 (the Slave 2) is running the DataNode

I know that the the Web Interface for the NameNode is running on Computer 1, on IP 0.0.0.0 and on port 9870 . Therefore, if I open the web browser on computer 1 (or on computer 2, or on computer 3), I will enter the 10.1.7.245:9870 on the URL bar (address bar) of the web browser to see the Web Interface of the NameNode.

======================================================

Now, I am using the web browser of my personal laptop.

How could I access to the Web Interface of the NameNode ?
