## Problem Background

Due to some impersonators mimicking user "kkk" escaping, you need to write a program to detect such impersonations.

## Problem Description

Given a username, it is considered an impersonation if it contains the substring `kkksc03`.

## Input Format

A string $s$ representing the username.

## Output Format

If it impersonates "kkk", output $\tt T$; otherwise, output $\tt F$.

## Samples

```input1
kkksc0303

T

kkk

F

kkksc03

T

kkksc02

F

This_is_not_real_kkksc03_yes

T

Data Range

$0 \le |s| \le 10^6$.

It is guaranteed that $s$ contains only printable characters.
