Problem:
 Score : 100 points    Problem Statement Joisino wants to evaluate the formula " A  op  B ".
Here, A and B are integers, and the binary operator op is either + or - .
Your task is to evaluate the formula instead of her.      Constraints  1≦A,B≦10^9  op is either + or - .         Input The input is given from Standard Input in the following format:  A  op  B       Output Evaluate the formula and print the result.        Sample Input 1 1 + 2      Sample Output 1 3  Since 1 + 2 = 3 , the output should be 3 .       Sample Input 2 5 - 7      Sample Output 2 -2
