I get the sense you are conditionally adding a value to the existing DRG rate so I'm expressing this as an adjustment that is typically zero. Either way your problem was mostly syntactical.

Well, based on the comments, it sounds a bit bizarre, but I'm sure there are reasons you can't go into the backstory or details.

I would say this.

SkipWhile(key => key != fromKey) is really the only way you can find a key for the purpose of finding more keys "after it", so in that sense, what you have is correct. If your keyspace is not ridiculously large, that seems sufficient.

That said, a different data structure would be better. For example, you could implement a concurrent version of a dictionary + array or dictionary + linked list that allows you to access a key in O(1) and then the subsequent elements in O(m) inside of a lock (you could even make it a ReaderWriterLockSlim). That avoids the O(n) scan to find the key if just using ConcurrentDictionary.

Insertion would be a bit strange, because you'd have to maintain a somewhat arbitrary notion of what before and after mean. In the dictionary + array case for example, you could add key 'foo' into the dictionary and into slot 0 in the array. Key 'bar' would go into the dictionary as usual, and into slot 1, and so on.

Oh - and your dictionary entry would have to point to the location in the array or the linked list to get that O(m), as well as the data itself. And, if you want to de-duplicate the data, the array/list could point back to the dictionary entry instead of just holding the data.

Arrays will leave you with holes when items are deleted! That's where a linked list would be helpful. Writes will be a bit slower to maintain "ordering" (using this term loosely) and because you are accessing two underlying data structures.

Apparently you can't get a range with 0 rows. In this method getRange(row, column, numRows, numColumns), every parameter should be a number larger than 0.

Why is rows.length 0?

The issue has to do with the fact that your JSON dataSet is not an array, therefore the for loop is terminated because dataSet.length is undefined. As a result row.length is zero because no values were added.

Assuming the first row (headers) in your sheet is:

companyId companyName articles.date articles.articleUrl articles.title articles.summary

You should map on the spellingWords array:

Are you sure you are running the project? It's still there (Xcode 12.0.1):

User input variables need to be called as input$abc.

Try this

I'm not sure what you mean by carve...

If carve==remove then you can use replace()

I think option 2 is the most easy and straight-forward one. You can put the 3 dataframes in a list and use lapply. You can pass an anonymous function in lapply to refer to the each cities dataframe inside the function.

strcpy is for copying strings, so you shouldn't use that for manipluating one character. It writes terminating null-character and results in destroying adjacent characters.
