23. Set Baud Rate Field in Control Register

    // Your code here
 uint32_t mask;
if(baud<0){
    return 0;
}
   mask=(( 1U << 4)-1 << 8);   /// for set lenght 

   reg&= ~mask; // clear reg 
    return reg |= (baud<<8)&mask;  //postion shift
}

int main() {
    uint32_t reg;
    uint8_t baud;
    scanf("%u %hhu", &reg, &baud);
    printf("%u", set_baud_rate(reg, baud));
