Problem

In this task Your program should solve a puzzle in the form :
a ? b == c
In this puzzle a, b and c are nonnegative integers and are given as standard input (0<=a,b,c<=1e3), and Your task is to say, which operations satisfy the equation, so the equality holds.
At your disposal you have discussed already operations in C++:
+ (addition)
- (subtraction)
* (multiplication)
/ (division)
% (modulo)

Your program should output a line with the solved puzzle, exchanging the ? symbol to the correct operation. the operation symbol and equality sign should be surrounded by single spaces.
We guarantee that for each puzzle there is at least one solution. If a puzzle has more than one solution, Your program should output ALL of them, in separate lines, in the order of equations described above.
