这是 #1:

输入：
a + (1 +5)
8
((a + 1 + 5))
1 + 5 + a
a + a + 1 + 1 + 5 + 6
a-(a + 1) + 1+1+5+12-12  +6-6+a-(8 -8)
1023 + a + 5 - 1022
6 -(6-(9-(9-(8-(5+8))))) -(a -5) +a +1+5+a
9+9+4+6+9+1-9-5-1-(8-7)
9999 + 9999+9999+9999-(9999 + 9999+9999+9999)+a+ 5
输出：
ABDEF

我的程序输出：

ABDEF

显示在第三列读到了C？ 难道是因为linux下的换行符和Windows不同吗？求大佬解答
