31. Rotate Left in an 8-bit Register

#include <stdio.h>

uint8_t rotate_left(uint8_t reg, uint8_t n) {
    // Your code here

    for(int i=0;i<n;i++){
        uint8_t temp = (reg >> 7) & 1;
        reg = reg << 1;
        reg = reg | temp ;
    }
    
    return reg;
}

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