Problem Statement

Given integer $x$, each pass prints the current value and then decrements it. Repeat while the updated $x>0$. Print all visited values on one line separated by single spaces.

Input

One line contains integer $x$.

Output

One line containing all printed values with exactly one space between adjacent values and no trailing space.

Subtasks

• Subtask 1 (20%): $-2\le x\le2$.
• Subtask 2 (30%): $-6\le x\le6$.
• Subtask 3 (50%): $-10\le x\le10$.

Examples

Example 1

Input

-1

Output

-1

Explanation

Print -1 on the first pass, decrement to -2, and stop.

Example 2

Input

3

Output

3 2 1

Explanation

The loop prints 3, 2, 1; after printing 1 the value becomes zero, so zero is not printed.
