This study kit encompasses all the topics and most of the common patterns for trees and graphs. The algorithms covered are DFS, BFS, traversals, Top sort, and disjoint union set.
I noticed that when starting with practice there is too much information out there. Additionally, most of the questions asked by companies these days are medium. Trying to solve medium problems directly can result in failure and will cause unnecessary frustration. I have found all the easy problems that can help understand the patterns. Additionally, I have also ordered the problems in a way that you practice one pattern over and over for 3 days to have recognition on it.
The study kit requires between 7-15 hours of time commitment depending on where you are at your interview preparation stage. POD is compulsory while POD++ is optional. If you are just starting out, stick to POD, if you are actively interviewing, aim for POD++
