    Or (Java) regex based solution:

    public class Solution {

    public static void main(String[] args) {
    int result = 0;
    Scanner scanner = new Scanner(System.in);
    Matcher matcher = Pattern.compile("(1+)")
            .matcher(Integer.toBinaryString(scanner.nextInt()));
    while (matcher.find()) {
        result = Math.max(matcher.group().length(), result);
    }
    System.out.println(result);
}

    }

    ** need to add two imports: import java.util.regex.Matcher; import java.util.regex.Pattern;
