Keep Only the Highest Set Bit

Code

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

// Complete the function
uint16_t highest_set_bit(uint16_t reg)

 {
    char count = 15 ;

    char n=0 ;
    
    while (n!=1)
    {
        uint16_t temp = (1<<count);
        if ( (temp & reg) == temp )
        {
            n=1 ;
            return temp;
        }
        else
        {
            count--;
         // return temp;
        }
 

    }

}

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

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