31. Rotate Left in an 8-bit Register

#include <stdio.h>
#include <stdint.h>

uint8_t rotate_left(uint8_t reg, uint8_t n) {
 
    // Your code here
   uint8_t left = (reg<<n)&0xFF;
   uint8_t right = (reg >> 8-n);
   return reg = left|right;

}

int main() {
    uint8_t reg, n;
    scanf("%hhu %hhu", &reg, &n);
    printf("%u", rotate_left(reg, n));
    return 0;
}
