[vaeng]

I will add list-ops

[vaeng]

I already started linked-list a while ago, so please don't start another. I promise to finish it soon 😃

[rajatnai49]

Hey, @vaeng I like to start contributing with the zebra-puzzle !

[vaeng]

Hey, @vaeng I like to start contributing with the zebra-puzzle !

Sure thing. Have fun and keep us in the loop. It's not an easy task, so there will be a lot of discussions and feedback.

If you l a pr early on, we can use it to keep track and you'll less likely have to redo things.

[rajatnai49]

Okay @vaeng I try my best.

[rajatnai49]

Hey @vaeng I opened pr but it closed automatically, can you guide me for what steps I have to follow for successfully open the pr

[ahans]

I can have a look at parallel-letter-frequency. There are a couple of options for implementing this. I would consider using something from the algorithms library together with a parallel execution policy to be the nicest modern C++ approach, so that's what I would go for.

[siebenschlaefer]

I can have a look at parallel-letter-frequency.

Good idea! I did look briefly at the C# version and the Go version. They seem to do similar things, using the mechanisms built into the language (PLINQ / Goroutines).
But I didn't understand how they actually test that. Good luck, have fun!

[siebenschlaefer]

I would like to contribute 'knapsack'.
See #795

[ahans]

Here goes a (draft) PR for parallel-letter-frequency: #800
Need some feedback to finish it up. Details in PR. Thanks!

[vaeng]

I will do dnd-character next.

[vaeng]

And yacht.

[vaeng]

I will do kindergarten-garden as well.

[ahans]

I will give spiral-matrix a go!

[ahans]

spiral-matrix is ready as #807.

[vaeng]

I'll do pig-latin next.

[ahans]

@vaeng I actually have it pretty much ready already. PR would come up later tonight. Sorry I didn't mention it here before.

Edit: pig-latin that is.

[ahans]

@vaeng Here is the draft PR: #811
If you read this too late and are done with yours already, feel free to just leave it closed.

[vaeng]

The last exercise has been merged. Thanks for all the effort, everyone!
