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 JavaScript (judge verdict: Accepted)

"use strict";
process.stdin.resume();
process.stdin.setEncoding('utf8');

var lines = []
var reader = require('readline').createInterface({
  input: process.stdin,
  output: process.stdout
});

reader.on('line', (line) => {
  lines.push(line);
});
/* 入力は 
 */

var re = /\s+|$/;
reader.on('close', () => {
    var l = lines[0].trim().split(re).map(Number);
    var n = l[0];
    
    aux(n);
});

function aux(n)
{
  var s='';
  for (var i=1; i<=n; i++){
    var x = i;
    if ( x % 3 == 0 ){
      s += " " + i.toString();
    } else {
      while (x > 0) {
	if ( x % 10 == 3 ){
	  s += " " + i.toString();
	  break;
	}
	x = Math.floor(x/10);
      }
    }

  }
  console.log(s);
}
