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,max_count=0;
    for(int i=0;i<=31;i++)
    {
        if(reg&(1<<i))
        {
            count=i;
        }
        if(count>max_count)
        {
            max_count=count;
            count=0;
        }
    }
    return reg&(1<<max_count);
}

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

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