QUESTION
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.
...ANSWER
Answered 2021-Jun-13 at 19:39You should try and reduce the repetition of calculations, so the maximum budget can be worked out before the foreach
loop. Also rather than have an if
to check if it's above this value, then use min
to take the lowest of the entry and the maximum budget
QUESTION
Sometimes in a HTML file, we have a
tag that shows the price of a product. For example the price is "1,200,000 Dollar"
. Now a user added this product to the cart. I want that the webpage display the total price in the cart.
Now in JavaScript I want the program separate the number of price from string and put that in a variable. Here in the example that I said the
tag shows "1,200,000 Dollar"
. Now I want to put just the number(in the example the number is 1,200,000
) in a variable to calculate the total price later.
What should I do?

I'd like to have a running year to date pct change column in my pandas dataframe:
Here is the dataframe:
...ANSWER
Answered 2021-Jun-12 at 14:49If I understand you well, you want the running percent change with respect to the last value of the previous year. It’s maybe not the most elegant, but you can explicitly build this last-value-of-previous-year series.
To start, you build a series with the date indices and years as values:

QUESTION
The code below is my current code
...ANSWER
Answered 2021-May-13 at 02:28I fix the ValueError and some other bugs, add more test cases.
- ValueError:After you add 10 and m1,you return a string like
$13.50
,which can't pass any if statement in your__radd__
method. So you got a ValueError inprint(10 + m1 + m2)
, which you attempt to add a string to a Money class. I fix it to return a Money instance and__repr__
to display the format you want. - The Money class only got
__radd__
method, which can't pass test case likem1 + 10 + m2
.I add__ladd__
method to handle it. - Also,the Money class don't have
__add__
method. I add it to handle test case likem1 + m2
Money2
not defined error.

You weren't very far wrong. The only changes that need to be made are in GetShoppingItem, which I show in full below. I have deliberately kept the changes to a minimum, in order to preserve as much of your logic as possible, so that you will better understand what is happening.
