Calculate the sum of two integers a and b, but you are not allowed to use the operator + and -.
Example:
Given a = 1 and b = 2, return 3.
java:
1 public class Solution { 2 public int getSum(int a, int b) { 3 int temp = a & b ; 4 if (temp == 0) 5 return a ^ b ; 6 else 7 return getSum(temp<<1,a^b) ; 8 } 9 }
