常用算法总结

int[] a = { 1, 2, 3, 4, 5, 9 };
            int[] b = { 1, 4, 5, 7, 8, 9 };
            string s_a = "";
            string s_b = "";
            foreach (int i in a)
            {
                s_a += i.ToString() + ',';
            }
            foreach (int i in b)
            {
                s_b += i.ToString() + ',';
            }
            string value = "不相同的元素：";
            foreach (int i in a)
            {
                if (!s_b.Contains(i.ToString()))
                    value += i.ToString() + ",";
