I'm not sure how should I unserstand the operations. What is the right output for the following input?
6
123
123
pxj
123
13
pxj
123
21
pxj
123
31
pxj
123
231
pxj
1
0
pxj
Are there any other special cases that I should handle?

You should read the input and output description carefully. Everything is said there.

The output for your test cases is obviously:
123
13
21
31
231
Impossible
But here is a tricky test case:
00
0
j
output should be: 00

Dyatlov - it wasn't clear to me that operations can be joined in any order.
Thank you Adrian for a great case. What about this one:
02001
21
j

I guess you wanted to see the answer for this case (the answer for your case is impossible):
02001
21
jx
my output is:
21

No, that's exactly what I wanted to know. I thought that 0, 0, 1 can be joined together into expression equal to 1 and then with 2 into 21 and then with 0. Thanks.
