if your goal is to finish dsa in 2 months and actually understand concepts deeply, i would honestly say go with striver a2z dsa sheet + playlist. it is probably the most complete and structured path for beginners to intermediate, especially if you are doing placements or interviews. concepts are explained well and the problem order is solid.

if you want deeper intuition for concepts, abdul bari is amazing for understanding things like trees, graphs, recursion, time complexity, and algorithms at a deeper level. for cpp-specific dsa, love babbar is also decent but can feel longer.

most important thing though, do not fall into tutorial hell. for every 1 hour of video, spend 2–3 hours solving problems. dsa only clicks when you struggle with problems, not when videos make everything feel easy. in 2 months, consistency matters more than finding the perfect playlist.
