For any integer n, the symbolic function (is defined as follows:
Please write a program to calculate the value of this function for any input integer.
Input format:
The input gives the integer n on one line.
Output format:
The function value corresponding to the integer n is output in a line according to the format "sign (n) = function value".
Input example 1:
10
Sample output 1:
sign(10) = 1
Input example 2:
0
Sample output 2:
sign(0) = 0
Input example 3:
-98
Sample output 3:
sign(-98) = -1
