GROKKING NOTES

I liked the way Grokking the coding interview organized problems into learnable patterns. However, the course is expensive and the majority of the time the problems are copy-pasted from leetcode. As the explanations on leetcode are usually just as good, the course really boils down to being a glorified curated list of leetcode problems.

So below I made a list of leetcode problems that are as close to grokking problems as possible.

Pattern: Sliding Window

• https://leetcode.com/problems/maximum-subarray/ # Close enough
• https://leetcode.com/problems/minimum-size-subarray-sum/

UPDATE (March 2020, thanks @ic): I don't know the exact AMI version but yum install docker now works on the latest Amazon Linux 2. The instructions below may still be relevant depending on the vintage AMI you are using.

Amazon changed the install in Linux 2. One no-longer using 'yum' See: https://aws.amazon.com/amazon-linux-2/release-notes/

Docker CE Install

sudo amazon-linux-extras install docker
sudo service docker start

Disable Slack notifications for the weekend

There isn't a way to configure DND for the weekend on Slack. However, you can use the /dnd 24 hours command to disable notifications for 24 hours using the [undocumented API][api] and [legacy tokens][token]. We're going to use the undocumented api and IFTTT to automate this.

Steps

1. Generate a [token] for your account
2. Navigate to your personal DM and copy the url (e.g. DAYM93S0N from acme.slack.com/messages/DAYM93S0N/convo/GBG661YR2-1536698414.000100/)
3. Update the following url with your information (TOKEN looks like xoxp-4030334043-4959593942-3030320302032-sdf23rfasdf23rsf and CHANNEL looks like DAYM93S0N)
