27. Extract Bit Field from 16-bit Register

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

uint8_t extract_field(uint16_t reg) {
    // Your logic here
    uint16_t mask=(1u<<5)-1;
    uint16_t result=(reg>>4)& mask;

    return result;
}

int main() {
    uint16_t reg;
    scanf("%hx", &reg);
    printf("%u", extract_field(reg));
    return 0;
}
