Subtasks

  • Subtask 1 — 100 points: −1018≤N≤1018-10^{18}\le N\le10^{18}.

Examples

Input

+17

Output

17

Explanation

The input text is +17, not yet an integer object. int() interprets the + sign and digits 1 and 7, producing the value 1717. Printing an integer uses the ordinary decimal representation, so the output is 17.
