23. Set Baud Rate Field in Control Register

    uint8_t j=0;
     for(int i=8;i<=11;i++)

        if((baud & (1<<j))!=0){
        reg|=(1<<i);}

        else if((baud & (1<<j))!=1){
         reg &= ~(1<<i);}
         ++j;
     }
    return reg;
}

int main() {
    uint32_t reg;
    uint8_t baud;
    scanf("%u %hhu", &reg, &baud);
    printf("%u", set_baud_rate(reg, baud));
    return 0;
