Keep Only the Highest Set Bit

Code

#include <stdio.h>
#include <stdint.h>
// Complete the function
uint16_t highest_set_bit(uint16_t reg) {
    // Your logic here
    int pos=0,gum;
    
    while(reg){    
    reg=reg&~(1<<pos);
    if(reg!=0){
        gum=reg;
    }
    pos++;
    }
    return gum;

    return 0;
}

int main() {
    uint16_t reg;
    scanf("%hu", &reg);

    uint16_t result = highest_set_bit(reg);
    printf("%hu", result);
    return 0;
}
