Problem Description

定义一个复数类Complex，重载运算符“+”，使之能用于复数的加法运算。参加运算的两个运算量可以都是类对象，也可以其中有一个是整数，顺序任意。例如：c1+c2、i+c1、c1+i均合法。（其中i是整数，c1、c2是复数），编程实现求2个复数之和、整数与复数之和。

Input

输入有三行：第1行是第1个复数c1的实部和虚部，以空格分开。第2行是第2个复数c2的实部和虚部，以空格分开。第3行是1个整数i的值。

Output

输出有三行：
第1行是2个复数c1和c2的和，显示方式：实部+虚部i
第2行是第1个复数c1加i的值，显示方式：实部+虚部i 
第3行是i加第1个复数c1的值，显示方式：实部+虚部i

Example Input

2 33 510

Example Output

5+8i12+3i12+3i
