Good luck
BTW on of the features of AdventOfCode is that we all get given different inputs so our answers will be different.
The examples are all the same but each of us gets different inputs for us to solve

This is my first successful run at part 1

Part 1

duration = 20ms

It is very much NOT the Snap! way do do it but it works

Hopefully, we'll see some much better solutions

You'll notice that I set the result to be a list. I do this, so I can easily copy and paste it into the AdventOfCode website

First successful run at part 2

part 2

Duration = 900 ms

Part 2

Part 1.

DeltaPlus

Part 2.

slidingSum, forcefully HOF styled

[loucheman]

HOF are very impressives ! 40ms VS 1400ms with a loop

Part 1

(1050ms with a warp)

(60ms)

Part 2

(3200ms with a warp)

(142ms)

i like all the solutions from everybody!

Can you edit your post to say me how much time it take to execute your code, i'm curious ! (with the big input)

I like your method of getting the averages.

I'd forgotten that in Snap! we don't have worry about asking for an item outside of the range of the list.

[cymplecy]

These look great - completely above my head though

And you've used recursion on day1 - Brian will like that

[loucheman]

Can you share the link to your project plz

[cymplecy]

Done
............

[dj_laser]

Just finished part 1

Part 1 Solution

Uses Recursion in a variable function so no messy inputs in block

Done part 2

Part 2 Solution

Unfortunately kinda slow

project here:Snap! 7 - dev - Build Your Own Blocks
