I am learning Dynamic Programming from freecodecamp, the instructor is using JavaScript and i know python so i am converting the logic in python.
Long story short, this problem's JavaScript implementation is working fine, but my python implementation is giving strange output.
I have matched the syntax many times and verified the logic, i can't point out where i am going wrong. Any help would be appreciated.
Problem Statement:
Create a program to find the smallest sub-array of integers whose sum is equal to targetsum

Answered 2022-Mar-29 at 08:34While an interactive debugger is the most general (and, often, most powerful) way of examining bugs, here a simple bit of scaffolding can reveal much. By adding a print(f"target = {targetsum}; memo = {memo}")
statement just before the end of bestsum

QUESTION
Hi guys so I can't seem to get the navbar
to remain at the top of the screen. If I use position: fixed
, the navbar
remains on top of the content so you can't see it. position: sticky
doesn't work. I presume this is due to having a set height on the body? Keen to know how to get this working with position: fixed
! Here is the code:
ANSWER
Answered 2022-Mar-13 at 15:59The easiest way by far is to use sticky position but on header
not on nav
. Because as element I am sticky as long as my parent is visible on the screen. And since the height of header
is not that big, it seems like having position:sticky
on nav
is not working. To know more about position sticky
, you could read here.
Here is the working example:

Hi guys I can't seem to center my button within the flexbox container class="hero". Any ideas why this is?
the button is below the email form but is left aligned to it (start in the same position).
I am trying to center the button like the example on this link:https://codepen.io/freeCodeCamp/full/RKRbwL. My CSS code also has a CSS reset but I haven't pasted that in. Thanks!

QUESTION
I have an app that opens the json version of a spreadsheet that I've published to the web. I used the instructions on this website: https://www.freecodecamp.org/news/cjn-google-sheets-as-json-endpoint/
It's been working fine for a couple months, but today I realized that the url of my json file is no longer working since yesterday. It gives the message, "Sorry, unable to open the file at this time. Please check the address and try again." The regular link to view the spreadsheet as a webpage still works though.
Did Google drop support for this feature? Is there another way to get the data of a spreadsheet in json format through a URL? I started looking into the Google Developer API, but it was really confusing.
...ANSWER
Answered 2022-Feb-04 at 08:57You are using the JSON Alt Type variant of the Google Data protocol. This protocol is dated and appears to no longer work reliably. The GData API Directory tells:
Google Spreadsheets Data API: GData version is still live. Replaced by the Google Sheets API v4.
Google Sheets API v4 is a modern RESTful interface that is typically used with a client library to handle authentication and batch processing of data requests. If you do not want to do a full-blown client implementation, David Kutcher offers the following v4 analog for the GData JSON Alt Type, using jQuery:
GData (old version, not recommended):
QUESTION
The code structure looks somewhat like this
...ANSWER
Answered 2022-Feb-26 at 05:59You could do that with CSS or the style prop in React.
I'm assuming your storing the state of the radio buttons somewhere?
When you map through the array, you can check if the current radio button's value is equal to the value of the current state. If they are the same, you can add the class or style to style the label.

command using the following:
ANSWER
Answered 2022-Feb-24 at 14:05Github Pages and gh-pages
are different things.
The gh-pages
npm package is a helper that makes it easy to create a (new) branch with your built source that is then used by github to host pages. This destination branch is called gh-pages
by default.
If you are trying to deploy the source from a different branch, then you can simply do:

I am trying to create a navigation bar with underline effect under each element when hovering over. For some reason the hover effect does not show up and I don't know if it's my code that's wrong or the browser and I have no idea how to fix it. The problem is the ".underline_indicators" class

Answered 2022-Feb-17 at 14:27With the code you gave us it doesn't work. But if you add as Doctype declaration before the
tag, it works fine. The code snippet works, because in the iframe the Doctype is added. I guess, the CSS can't validate without it.
QUESTION
I have a Firebase real-time database integrated with React Native where I can create users. But my problem is that when I try to log in I get an error. I run my app on IOS if it makes any difference. I have followed this guide: How to Build a React Native App and Integrate It with Firebase. I use the method Email/Password for login. I use Firebase version 9.6.4.
I have looked through this thread: Could not reach Cloud Firestore backend. and tried all the solutions but nothing works for me.
Any suggestions on what possibly could cause the error and how do I solve it?
Error message:

If you enabled this API recently, wait a few minutes for the action to propagate to our systems and retry. This typically indicates that your device does not have a healthy Internet connection at the moment. The client will operate in offline mode until it is able to successfully connect to the backend.

Answered 2022-Feb-10 at 05:23Your error message says FirebaseError: [code=permission-denied]: Cloud Firestore API has not been used in project xxxx before or it is disabled.
The app tries to read a user document after signing in, but seems to have no access.
Check your firestore rules in your firebase console to see if read rules are valid. Firestore may have initialized with rules that allow only admin users to read/write, or rules that allow all read/write only for a month after its creation.
To make your app work, your firestore rules need to allow read access on users collection. Here are the rules you can set on your firestore. The more specific rules you set, the more secure the app is.
Allow unauthenticated access on all collections
