This is the real content which gives us the technical skills we need..

Thanks.

[@rohitgupta7037]

Very good explanation. I tried to understand this logic in so many videos/code but was not able to follow until I saw this video. Thanks !!!

[@chetanshrivastava3762]

Very nice explanation sir...first solution which comes to me is to use builtin function..(return int('{:032b}'.format(n)[::-1],2)) which is very easy(convert integer into 32 bits binary,reverse & convert into integer ).

hats off!!!.. every single day you show up !!!

It may not be possible every day in future. But, will be try to do so as much as I can.

@@KnowledgeCenter Sir pls solve Graphs problems as much as possible because on youtube there is no much content available on Graphs and Obviously the way you explained is SUPERB, Thankyou so much Sir.!!!

@@KnowledgeCenter please don't say this sir. at least keep posting the solutions of daily challenges.
after brainstorming for 1 hour even if I solve the problem I wait for your video because you always come up with an extra approach.

On youtube videos having Tips and Tricks sell more. People are looking for some shortcut, some magic trick. But, there is generally no shortcuts to learning & mastering concepts. One has learn everyday and practice every day. Yes, some guidance and mentoring is required. But, mostly it will be driven by yourself. Your Will.

i converted the bit to string using bitset and reversed it but how to convert it back to uint?????

[@rainethai4357]

approach 2 (bit masking) can't be done in java. do you know why?

[@manasdeora4601]

why?

Thanks.

[@prabhatchanchal]

C++
bitset x(n);
auto str = x.to_string();
std::reverse(str.begin(), str.end());
auto y = std::bitset(str);
return (uint32_t) y.to_ulong();
Java
String bin=Integer.toBinaryString(n);
bin=new StringBuilder(bin).reverse().toString();
return Integer.parseInt(bin,2);
but same logic not worked in java.
because java do not have unsigned type :(

[@KnowledgeCenter]

Great, you tried. Thanks for sharing.

@Prabhat. You don't need to code in multiple languages, you can choose 1 language.
