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	position;

	// Your logic here
	position = 0;
	for (int i = 15; i >= 0; i--)
	{
		// printf("position in binary:%b\n\r", 1 << i);
		if ((reg & (1 << i)) == (1<<i))
		{
			position = i;
			i = 0;
		}
		else
		{
			position++;
		}
	}
    
	return (1<<position);
}

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

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