Least Significant Bit
The Least Significant Bit (LSB) is the rightmost bit in the binary representation of a number. It holds the least value, representing either 0 or 1 in the number’s total value. The LSB is crucial in several computing operations such as bit manipulation, steganography, and some errorchecking algorithms. In an (n)bit number, the LSB represents (2^0) or 1.
Example Code
Java
In Java, you can find the value of the LSB using bitwise AND operation.


n & 1
: Bitwise AND operation to isolate the LSB.
C++
In C++, the method to find the LSB remains the same as in Java.


n & 1
: Bitwise AND operation to isolate the LSB.
Python
Python also allows for a straightforward way to find the LSB.


n & 1
: Bitwise AND operation to isolate the LSB.
Key Takeaways
 The Least Significant Bit (LSB) is the rightmost bit in a binary number and represents the smallest value.
 The bitwise AND operation with 1 (
n & 1
) helps quickly isolate the LSB.  The operation to find the LSB is simple and consistent across Java, C++, and Python.
