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
 
 uint16_t result = 1U<<15;

for (int i=0 ;i<16;i++){
   
    if ((reg & result)== 0){
         
     result = result>>=1;
    }

} 
return result;


}

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

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