思路：模拟。

AC代码：

 #include<bits/stdc++.h>
 using namespace std;
 int main()
 {
     int x,y,z;
     while(cin >> x >> y >> z)
     {
         if(x == y)
         {
             if(z == ) cout <<  << endl;
             else cout << "?" << endl;
         }
         else if(x > y)
         {
             if(x - y > z) cout << "+" <<  endl;
             else cout <<  "?" << endl;
         }
         else
         {
             if(y - x > z) cout << "-" << endl;
             else cout <<  "?" << endl;
         }
     }
     return ;
