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 limit=32768;
    int temp=0;
    for(int i=0;i<16;i++){
        if((limit&(reg<<i))==limit){
            temp=limit>>i;
            break;
        }
    }
    return temp;
}

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

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