This is a pretty terrible explanation Too many gaps

Very clear People disliking it should not do programming

This is so confusing 🤣 even he doesn't know what he's doing
Comment from : Sanjeev Singh

is there any recursion solution for this if it is there please put sir
Comment from : Kushwanth Kapa

For anyone reading this comment, please try and learn how we come up with these solutions Don't mug it up like the guy in the video The solution is actually very intuitive and once you understand WHY this works, you will never forget it and will be able to solve other questions that are similar to this one

how can we get a total of 0 in 1 way ?

Thank god I skipped the whole video and just wasted 20 seconds and the time to put a comment for the greater good

Let's fill this column with 0, let's fill this column with 1that tells everything about the lecture No intuition, no logic only ratttta

2:12🤣🤣🤣🤣 he doesnt know why he is doing this🤣🤣

this is irritating!
Comment from : Rishabh Ratan

Its just like he has mugged up all the algorithm before this video and just gulped out whole in front of camera
Comment from : TANMAY AGARWAL

He explained how the algorithm works, but he didn't explain how one can come up with such tabular solution Promotes memorization rather than analysis

i might be wrong but let me take a stab at it if i want to solve the very last cell which is the last row and column, i think it is saying that we know how to get 5 from the other 2 coins and that answer is 3 ways to get 5 from just the other 2 coins now we still have to add how many ways we can get to 5 using the third coin as well so we know that the last coin has a value of 3 what is the amount we need to get from the value of the coin which is 3 to the total we want which is 5 that answer is 2 we need to find out how many different ways can we make 2 using the last coin in order to reach the final total of 5 therefore we back into it by taking the total of 5 minus the value of the last coin 3 to get the amount we need which is 2 and we can see that there are 2 ways for us to make 2 so we add that 2 to the other ways we made 5 with the other coins thus the final answer is 3 ways to make 5 using the other 2 coins plus 2 ways to make 2 using all the coins brings us to the final answer of 5 ways to make 5 using all the coins the reason we don't have to find other ways is because we already solved the overlapping subproblems so they are already included in our final answer sorry if this doesnt make any sense to you, but writing this comment actually helped me understand it better, lol peace out
