[SoumyaSura-my]

Thank you for explaining in very easy manner

[showme]

Excellent explanation. Even a nontechnical guy like me can comprehend easily. Thanks a lot, sir

[kennyi]

I liked here StringBuilder option the most. For 12300 it returns us 00321 but Option1 - Modulus one returns just 321 which is not good. Also, for numbers more than 9-10 digits Option 1 doesn't work but StringBuffer and StringBuilder comes over well . Thanks for the video !

[pavanichella]

I always wanted these logics.Guess i found the right channel .Thanks a ton sir!

[priyankajadhav]

You are best teacher in the world, yours teaching skills is awesome sir

[nayabshaik]

Great thanks you sir ☺. You are simply awesome.. coding med interest leni naaku, meerichhe explanation tho interest vachhestundi.. I am practcing well. Once again Thank you very much sir 🙏

Hello, I think 2nd and 3rd methods are same. I think 3rd one can be like converting number to string and then using charAt method to extract each char and then appending to the sting builder
int origNum = 123456;
String stNum = String.valueOf(k);
StringBuilder revStg = new StringBuilder();
for (int i = stNum.length()-1; i>=0;i--)
{

}

System.out.println(revStg);

}

}

My exams are nearing and I found this video. This is so useful. Thank you sir

[vishalbandi]

i think we can also reverse integer or string by using FOR loops ...

[hemmishra]

Thank you, I was looking for such series in hindi.
Thank you again

[gauri]

You explain it the best way thanks a lot sir...

[calsoftdev]

your explain is very clear, it ease to understand

[busisiwemailula]

Thank you so much ❤did this for my assignment

[ashokkadam]

Very Nice Explaination...Thank You Sir...!!!

[whatisinthenameshakespeare]

I think the input taken sc.nextInt can result in exception if user enters non number or mixed input... we should handle it in a better way

[nvr]

Hi Bro, There is one more way
public static String reverseNum(int num) {
String reverseString = "";
String str = Integer.toString(num);
char[] chr = str.toCharArray();
for (int i = 1; i <= str.length(); i++) {
reverseString += chr[str.length() - i];
}

return reverseString;

}

[sasikumarchunduri]

Thank you so much very clear explanation

[vivekayadi]

Explanation is excellent but, the xor u said that is not correct it would be bidirectional then if the values are same its 1 otherwise its 0

[akshayar]

thank you sir for this explanation it is really helpful, i have doubt if we dont use scanner class is there any mistakes
