Keep Only the Highest Set Bit

Code

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

// Complete the function
uint16_t highest_set_bit(uint16_t reg) {
    uint16_t count =0;
    uint16_t s=reg;
    if (reg !=0) {
    while ((s/2)>=2) {
        s=s/2;
        count++;
    }
    reg =(1u<<(count+1));
    }
    // Your logic here
    return reg;
}

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

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