Extract and Modify Field in a 32-bit Register

Code

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

uint32_t update_register(uint32_t reg) {
    // Your logic here
    uint32_t mask = 1U << 10;
    if (((reg >> 10) ^ 0x1F) != 0){
        while (reg & mask){
            reg ^= mask;
            mask <<= 1;
        }
        reg ^= mask;
    }
    return reg;
}

int main() {
    uint32_t reg;
    scanf("%u", &reg);
    uint32_t updated = update_register(reg);
    printf("%u", updated);
    return 0;
}
