Lamp Status Checker

You are given a binary string of length 3, where each character represents the state of a switch (with '1' indicating the switch is on and '0' indicating it is off). The lamp turns on if at least one switch is on. Formally, if the input string is S = s₁s₂s₃, then the lamp is ON if \(\exists i \ (1 \leq i \leq 3)\) such that \(s_i = 1\). Otherwise, the lamp is OFF.

Your task is to implement a program that reads the binary string from standard input and outputs the status of the lamp.

inputFormat

The input is provided via stdin as a single line containing a binary string of exactly 3 characters (each character is either '0' or '1').

outputFormat

Output a single line to stdout: "ON" if at least one character in the input is '1', otherwise output "OFF".
