23. Set Baud Rate Field in Control Register

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

    // Your code here
    uint32_t reg1 = 0, reg2 = 0;
    for(uint8_t i = 0; i < 4; i++){
reg1 |= (1 << i);
    }
reg1 <<= 8;
reg &= ~(reg1);
reg2 = baud << 8;
reg |= reg2;

    return reg;
}

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