Great video. Subbed and liked. All my CS classes have me coding C and C++. So far I'm able to understand your coding example. What I'm really after is help writing a recursive function to find unique combinations of K elements from a list of N elements. I have to write it in C and then translate to x86 assembler. Do you know where I can find some good information on how to write a recursive algorithm for this in C. The ChatGBT solution wraps recursion in a for loop. I would love a walk-through of what's happening on the stack.

That time complexity is wrong. It is exponential not linear

5:09 this is probably the shortest and easiest way to understand on how to build the recursive call. Thanks!

any chance you'll add R to your website code options?

I love the Dynamic programming video of yours.. It is easy for me to follow and understand rather than buying some paid courses.. It worth the time!
