I am reading Data Structures and Algorithms for quite some time. Today i started graphs. I start of with basic concepts in graphs like adjacency matrix , adjacency list on.. I find difficulty in coding the concepts. My preferred language is C++. Should i concentrate only on interview problems then? or go slow with all concepts in graphs. But i am worried if i get any interview calls in between and if i go slow.. please provide your suggestions. I watch abdul bari sir videos to learn graphs. Any other material?
