If the integer's last digit is 0, what should the output be? ie, cases such as 10, 100. Did you notice that the reversed integer might overflow? Assume the input is a 32-bit integer, then the reverse of 1000000003 overflows. How should you handle such cases? For the purpose of thi...

That's all abouthow to reverse bits of an integer in Java.This is the brute force solution and there are some clever solutions also possible using a bitwise operator. If you know one, feel free to post in the comments, that will help our readers a lot. I'll also be going to update...
