23. Set Baud Rate Field in Control Register

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

uint32_t set_baud_rate(uint32_t reg, uint8_t baud) {
    // Your code here
   // reg = (reg & ~(((1U<<4)-1)<<8))| ((baud &((1U<<4-1)))<<8);
   uint32_t mask=((1U<<4)-1U)<<8;
   reg &= ~(mask);
   reg |= (baud << 8)& mask;
    return reg;
}

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