This week, we are looking at a few accounts. In this set of data, there are 4 accounts. The first row of every account represents the number of credits/debits against the account, and the second row represents the actual credits and debits paid against the account in the order they were paid. Your task is to find the credits and debits where the sum of debits and credits BEFORE any transaction is equal to the sum of debits and credits AFTER it. Please count the transactions from 0 to match the answer. Below is a picture that illustrates the logic of which transactions should be captured. The picture represents the second account.
Opted for a solution that calculates running total from Left-to-Right and then re-sorts to calculate from Right-to-Left, and then filtered for only those options that had the same total in both directions.
I like the way that you eliminated the noise that @JoeM inserted into the problem. I also learned from your use of the parse that instead of \s you could literally use a space character. I don't like it, but it is possible.
Good luck in the Grand Prix!

I periodically go rogue on the shortcuts with syntax, though probably not as intentionally as you might think haha... In this case, I didn't even think to use \s. It's been that kind of Monday. You get a gold star for catching onto that though! :)
