Bit flipping is a simple operation in computing where the value of a single bit is changed from 0 to 1 or from 1 to 0. This process is fundamental in digital systems, as bits are the basic units of information in binary code. Flipping a bit can be used for various purposes, such as error correction, data manipulation, and encryption. In programming, bit flipping can be achieved using bitwise operators. For example, the XOR operator can flip a specific bit in a binary number. This technique is often utilized in algorithms and data structures, making it an essential concept in computer science and information technology.
