[問題] 大數相加 - 測試+Debug
題目：
A char array can be used to store large integers one digit at a time.
For example, the integer 1234 can be stored in the array a by
setting a[0]=’1’, a[1]=’2’, a[2]=’3’, a[3]=’4’.
Write a program that reads in two positive integers, then outputs the sum of
the two integers.
The program using std::vector and without limitation.
In addition, allow the integers to be negative numbers.
簡單來說就是做無限位數(大數)的加法，允許有負數。

有興趣的板友可以幫我想測資，檢查有無問題。
或者可以建議此程式有無任何改進的空間，小弟蠻需要學習的。
基本上已經完成一些簡單的錯誤偵測
可檢查
1. 輸入0~9以外的數字
2. 開頭為0的數字 ex. 09923, -0827429, 是不合法的.
