Code

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

uint32_t update_register(uint32_t reg) {
    // Your logic here
uint32_t value;
value=((reg>>10&((1U<<5)-1)));

if(value<31){

    value=value+1;

    reg&=~(((1U<<5)-1)<<10);
    reg|=(value<<10);
}


    return reg;
}

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