Logical Negation

Version: Phuoc Hung OJ Extended

Problem Statement

Given an integer $x$. In C conditions, zero is treated as false and every nonzero value is treated as true. Determine the logical value of !x.

Input

A single line contains the integer $x$.

Output

Print TRUE if !x is true; otherwise print FALSE.

Subtasks

• Subtask 1 (20 points): $-10\le x\le 10$.
• Subtask 2 (30 points): $-100\le x\le 100$.
• Subtask 3 (50 points): $-1000\le x\le 1000$.

Examples

Example 1

Input

0

Output

TRUE

Explanation

In C, zero is false and any nonzero integer is true. With x = 0, !x is true, so the output is TRUE.

Example 2

Input

-1

Output

FALSE

Explanation

In C, zero is false and any nonzero integer is true. With x = -1, !x is false, so the output is FALSE.
