17 Reverse Bits | LeetCode | Java Solution in Hindi

The intuition behind solving the reverse bits problem is to iteratively process each bit of the given integer and construct the reverse binary representation of that integer. Here's a step-by-step approach to solve the problem:

Iterate through each bit: Start from the rightmost bit (least significant bit) and iterate towards the leftmost bit (most significant bit).
Extract the current bit: At each iteration, extract the current bit from the given integer. You can do this using bitwise AND operation with a bitmask that has only the current bit set to 1.
Append the bit to the result: Append the extracted bit to the result by shifting the result one position to the left and adding the extracted bit to the rightmost position.
Repeat until all bits are processed: Continue this process until you have iterated through all the bits of the given integer.
Return the result: Once all bits are processed, the result will be the reverse binary representation of the given integer.
Here's a more detailed breakdown of the approach:

Initialize a variable to store the result.
Iterate through each bit of the given integer, starting from the rightmost bit.
At each iteration, extract the current bit using a bitmask and bitwise AND operation.
Append the extracted bit to the result by shifting the result one position to the left and adding the extracted bit to the rightmost position.
Repeat this process until all bits are processed.
Return the result, which will be the reverse binary representation of the given integer.
This approach efficiently reverses the bits of the given integer using bitwise operations without needing to convert the integer to a string or array of bits. It has a time complexity of O(log n), where n is the number of bits in the integer.
