Code

#include <stdio.h>

typedef struct {
    unsigned short reg;
} ConfigRegister;

int validate_config(ConfigRegister *cfg) {
    // Write logic using pointer access
    //My approach
    // if((cfg->reg & 1) && (((cfg->reg)>>2) & 3) < 3 && !(((cfg->reg)>>4)&1)  )
    // {
    //     return 1;
    // }
    //Default
    if((cfg->reg&1)==0)
    {
        return 0;
    }
    if(((cfg->reg >> 2) & 3) == 3)
    {
        return 0;
    }
    if((cfg->reg >> 4) != 0)
    {
        return 0;
    }
    return 1;
}

int main() {
    ConfigRegister cfg;
    scanf("%hx", &cfg.reg);

    int result = validate_config(&cfg);
    printf("%d", result);

    return 0;
}
