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;
    while (reg >1){
        reg = reg >> 1;
        count++;
    }
    if (reg != 0){
        return (1<< count);
    }
    else{
        return 0;
    }
}

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

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