Problem:
Structured Programming

In programming languages like C/C++, a goto statement provides an unconditional jump from the "goto" to a labeled statement. For example, a statement "goto CHECK_NUM;" is executed, control of the program jumps to CHECK_NUM. Using these constructs, you can implement, for example, loops.

Note that use of goto statement is highly discouraged, because it is difficult to trace the control flow of a program which includes goto.

Write a program which does precisely the same thing as the following program (this example is wrtten in C++). Let's try to write the program without goto statements.

void call(int n){
int i = 1;
CHECK_NUM:
int x = i;
if ( x % 3 == 0 ){
cout << " " << i;
goto END_CHECK_NUM;
}
INCLUDE3:
if ( x % 10 == 3 ){
cout << " " << i;
goto END_CHECK_NUM;
}
x /= 10;
if ( x ) goto INCLUDE3;
END_CHECK_NUM:
if ( ++i <= n ) goto CHECK_NUM;

cout << endl;
}

Input

An integer n is given in a line.

Output

Print the output result of the above program for given integer n.

Constraints

3 ≤ n ≤ 10000

Sample Input

30

Sample Output

3 6 9 12 13 15 18 21 23 24 27 30

Put a single space character before each element.

Solution in Ruby (judge verdict: Wrong Answer)

n=gets.chomp.to_i
for i in 1..n do
  if i%3==0 then
    print " #{i}"
  else
    if i%10==3 then
      print " #{i}"
    else
      if i/10==3 then
        print " #{i}"
      else
        x=i/100
        if (i-x*100)/10==3 then
          print " #{i}"
        else
          if i-300>0 && i-300<100 then
            print " #{i}"
          else
            if i-3000>0 && i-3000<1000 then
              print " #{i}"
            end
          end
        end
      end
    end
  end
end
print "\n"
