371. 两整数之和

不使用运算符 + 和 - ，计算两整数 ​​​​​​​a 、b ​​​​​​​之和。

示例 1:

输入: a = 1, b = 2
输出: 3

示例 2:

输入: a = -2, b = 3
输出: 1

public class Solution371 {
	public int getSum(int a, int b) {
		while (b != 0) {
			int brw = a & b;
			a = a ^ b;
			b = brw << 1;
		}
		return a;
	}

	public static void main(String[] args) {

		Solution371 sol = new Solution371();

		int a = 1, b = 2;

		System.out.println(sol.getSum(a, b));
	}
}
