I was unable to fully make it by myself, kind of had the same approach but more complicated and less functional, learned a lot from your approach thank you!

[vishal]

Loving these problem solving videos. Keep 'em coming :D

[SomeoneAlive]

Love this channel! <3 Amazing explanations, intuitive approach to solutions. I wish you create a playlist on how to tackle Graphs, DP, Backtracking topics. Your teaching style is awesome!

[arpitagarwal]

You start recording more question like this and solve them will help us get different approach .
thanks

[DougieMuringani]

Thank you. this is the simple approach with a good explanation, but you will use less memory and less time if you use arrays, I think the (hashed) map lookup is a bit more expensive in this respect. since we will be using a fixed size small array of constant values/chars. However, this solution is correct.

CCXLVIII = 248 u have shown CCXLVII i.e 247 however that doesn't affect anything but thanks keep making this kind of problem solving videos

[ritikbhardwaj]

Really thanks man, for this so crystal clear explanation.... my first video forced ....me to hit subscribe...thanks again...

[SurendraBabuK]

Please continue for some more questions. It's really appreciate your efforts

[namratam]

Please upload problems related to dynamic programming and greedy approach and divide and conquer, Huffman coding.. i am grateful to you for this incredible video.

[namratam]

This made me take more interest in programming

[GagandeepSingh-lzbg]

Very good explanation, to the point. Thank you.

[saddamahmad]

thank you very much sir for this video

[caseycampbell]

Honestly this is the first time I've understood this problem after watching this video. Great explanation!

[adeshgaikwad]

Doesn't he sounds like Rohit from Koi Mil Gaya...Aaila Jaadu

[shubhamsaurabh]

Sir please make a video on how to get all permutations of a string.
Please solve it without recursion.

[learntech]

Please cover strings, arrays, collections use of construcors, if very strong oops and some concepts, the main idea can be or agenda can be your explanation /easy way can boost confidence to code

[SuperYouthful]

Int number = 0;
Char[] roman = RomanNum.getChar();
For(int I = 0, i++, i< roman.length())
{
Switch roman[i] {
Case: "M"
NUMBER += 1000;
CASE: "V"
Number += 5;
... }
Return new Integer(number);
