You are given an 8-bit register and a number of positions n. Rotate the register to the left by n bits. The rotation must be circular, meaning the leftmost bits wrap around to the right.
Use 0-based indexing, and return the result as an 8-bit value.
Example 1
Input: reg = 0b1011 0000, n = 1
Output: 0b0110 0001
Example 2
Input: reg = 0b1000 0001, n = 2
Output: 0b0000 0110
Example 3
Input: reg = 0b1111 1111, n = 4
Output: 0b1111 1111
Input
