Package for this problem was not updated by the problem writer or Codeforces administration after we’ve upgraded the judging servers. To adjust the time limit constraint, solution execution time will be multiplied by 2. For example, if your solution works for 400 ms on judging servers, then value 800 ms will be displayed and used to determine the verdict.

standard outputThe Little Elephant has an integer *a*, written in the binary notation. He wants to write this number on a piece of paper.

To make sure that the number *a* fits on the piece of paper, the Little Elephant ought to delete exactly one any digit from number *a* in the binary record. At that a new number appears. It consists of the remaining binary digits, written in the corresponding order (possible, with leading zeroes).

The Little Elephant wants the number he is going to write on the paper to be as large as possible. Help him find the maximum number that he can obtain after deleting exactly one binary digit and print it in the binary notation.

Input

The single line contains integer *a*, written in the binary notation without leading zeroes. This number contains more than 1 and at most 10^{5} digits.

Output

In the single line print the number that is written without leading zeroes in the binary notation — the answer to the problem.

Output

11010

Note

In the first sample the best strategy is to delete the second digit. That results in number 11_{2} = 3_{10}.

In the second sample the best strategy is to delete the third or fourth digits — that results in number 11010_{2} = 26_{10}.
