islands | An example of Simplex noise with phaser to construct islands | Learning library

I am coding a solution program for leetcode. I have encountered memory read errors and segmentation fault errors which I am unable to resolve. I have tried tinkering with the code to try and remove the errors.
For example: in the numIslands function's last lines, I had tried declaring coordinates as an array rather than a pointer but the results did not change.
*(last + 1) = *(coordinates + 1); does not seem to work at all in the numIslands function. I am totally blank about what to do next.

I have loop like

I am trying to solve a "gaps and islands" by date issue I'm facing (kudos to Gordon Linoff helping me identify this issue). I want to group the below table by person, office and job while respecting order by person,from_date. consider the table below:

I would like the last field to have 50px border radius on the right. Why is this not working?

I have an object with 2 properties available - timestamp and timezone, and they usually look something like this:

So I have a data frame like this

I have a table where there are 2 date columns out of a total of 4 - valid_from_dt and valid_to_dt. Other 2 columns are itm_no and price. I need to find the max of valid_to_dt in the group of itm_no, price and a continuous series of date. This will use some extent of gaps and islands solution. Then gotta display that max value in all rows of that group. I will share the code of the table.

i am using python json and i want to let my Python code search for specefic Keywords in a JSON-File.

Basically it should search for the "profilename" and then go one line down and print the email of the profile out.

I am new to api stuff and have come across a small piece of code in python to retrieve data which I would like to replicate in r:

python code:
