The first round was honestly not that bad- lc easy and med and sticking to array and 2 ptr. Are the second round problems harder and do they have expanded scope to include stacks, trees, graphs, combinations/backtracking etc? Should I just do as many meta tagged lc problems as I can cram in? Any tips are much appreciated! Targeting E5 role. Thanks!
My screen included a BFS problem.
Thanks! Trees or graphs?
Right side view of a tree. 199.
Just do the meta tagged LC questions sorted by frequency in the last 6 months.
They will be at same level. Meta tagged Lc problems are enough!
