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 count=0,temp=0;
    temp=reg;
    while(reg>1)
    {
    reg=reg/2;
    if(reg>=1)
    count++;
    }
    return temp&(1<<count);
}

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

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