This can be useful in a variety of contexts, such as in computer science and cryptography. The program will take an integer input and a rotation distance, and will output the resulting rotated number.

WebA few miscellaneous notes about bit operations as you practice further: operator precedence with bit operators and other operators can be tricky. Always use parentheses where precedence is ambiguous just to make sure operators execute in the order you expect. For instance, 1<<2 + 3<<4 means 1 << (2+3) << 4 due to precedence rules.
