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 C (judge verdict: Time Limit Exceeded)

#include<stdio.h>
int main(void){
	int i = 1;
	int n;
	scanf("%d\n",&n);
	int x ;
	for(i=1;i++;i<=n){
		x = i;
		if(x % 3 == 0){
			printf(" %d",i);
		/* }
		else {
			while(1){ */
				if(x % 10 == 3){
					printf(" %d");
					/*break; */
				}
				/* else{
					x = x/ 10;
					if(x==0) break;
				} 
			}*/
		}
	}
	printf("\n");
	return 0;
}
