Someone bought flowers, how nice.
You look around on the table and find a logbook.
It's just a bunch of numbers in a row.
It seems that each number is the number of euros spend on some item.
Each shopping session (where multiple items were bought) are grouped together.
The shopping sessions are separated out by NAs.
For example, if the logbook said: 10, 7, 12, NA, 8, 9, then there were two sessions.
In the first session, three items were bought for 10 + 7 + 12 = 29 euros in total.
In the second session, two items were bought for 8 + 9 = 17 euros in total.
The entire logbook that you found is stored in `shopping.rds`.
Load it in. Your goal is to find the session where the most money was spend in one session.
The amount of money that was spend in that session is the new hidden word.

Where do you want to go?
