main thing is i wanna visualize like in that table form from where to where we are moving then simply just keep it in words yeah forsure ill practice more dp problems from tomorrow but today i need to know where should i just brush my concepts better
I've been using USACO Guide's dp section for tutorials and cses and atcoder's dp contest for problems. Might be useful.
This series contains 12 DP (1D DP to Graph DP) patterns from basics + master tabulation (bottom-up) → Memoization → Bottom-up → Space optimizations → Multiple ways to solve + intuition building + diagrammatic explanations + time & space detail → Learn how problems give hints to think recursively → Learn how to identify loops in recursion → Learn everything you need to know about DP
