Rng is going to a festival.

The name of the festival is given to you as a string S, which ends with FESTIVAL, from input. Answer the question: "Rng is going to a festival of what?" Output the answer.

Here, assume that the name of "a festival of s" is a string obtained by appending FESTIVAL to the end of s.
For example, CODEFESTIVAL is a festival of CODE.

Constraints

9 \leq |S| \leq 50

S consists of uppercase English letters.

S ends with FESTIVAL.

Input

Input is given from Standard Input in the following format:

S

Output

Print the answer to the question: "Rng is going to a festival of what?"

Sample Input 1

CODEFESTIVAL

Sample Output 1

CODE

This is the same as the example in the statement.

Sample Input 2

CODEFESTIVALFESTIVAL

Sample Output 2

CODEFESTIVAL

This string is obtained by appending FESTIVAL to the end of CODEFESTIVAL, so it is a festival of CODEFESTIVAL.

Sample Input 3

YAKINIKUFESTIVAL

Sample Output 3

YAKINIKU
