26. Extract and Modify Field in a 32-bit Register

#include <stdio.h>

uint32_t update_register(uint32_t reg) {
    // Your logic here
    uint32_t mask = (0x1F) << 10;
    uint32_t field = ((reg >> 10) & 0b11111);
    if (field < 31) {
        field++;
    }
    uint32_t ans = (reg & ~mask) | (field << 10);
    return ans;

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