The expression “x&2” is a bitwise AND operation in many programming languages, including languages like C, C++, Java, and others. In this context:

If “x” is a binary number, the bitwise AND operation with 2 (binary 10) will result in a number where only the bit corresponding to the second least significant bit of “x” is retained.

If “x” is a decimal number, the operation “x & 2” checks whether the second least significant bit of “x” is set (equals 1) or not (equals 0).

For example, if x is 5 (binary 101), then “x & 2” would be 0 (binary 000) because the second least significant bit is not set.

If x is 6 (binary 110), then “x & 2” would be 2 (binary 010) because the second least significant bit is set.
