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.

Step 1 (Creating a bootable macOS Sierra ISO for VirtualBox):

1. hdiutil attach /Applications/Install\ macOS\ Sierra\ Public\ Beta.app/Contents/SharedSupport/InstallESD.dmg -noverify -nobrowse -mountpoint /Volumes/install_app
2. hdiutil create -o /tmp/Sierra.cdr -size 7316m -layout SPUD -fs HFS+J
3. hdiutil attach /tmp/Sierra.cdr.dmg -noverify -nobrowse -mountpoint /Volumes/install_build
4. asr restore -source /Volumes/install_app/BaseSystem.dmg -target /Volumes/install_build -noprompt -noverify -erase
5. rm /Volumes/OS\ X\ Base\ System/System/Installation/Packages
6. cp -rp /Volumes/install_app/Packages /Volumes/OS\ X\ Base\ System/System/Installation/
7. cp -rp /Volumes/install_app/BaseSystem.chunklist /Volumes/OS\ X\ Base\ System/BaseSystem.chunklist
