public class Main {
    public static void main(String[] args) {
        int number = 125; 
        
        System.out.println(String.format("%32s", Integer.toBinaryString(number)).replaceAll(" ", "0"));
        System.out.println(number);
        
        number = ~number; 
        
        System.out.println(String.format("%32s", Integer.toBinaryString(number)).replaceAll(" ", "0"));
        System.out.println(number);
    }
}
