Imagine you need to subtract one number from another using MATLAB.
You will not be using eval for this task.
Given two ASCII strings representing two integers X and Y.
Each of them has only 12 or less ASCII characters.
Each of them represents signed integers, such as '+2345'
Please output the result of (X-Y) in a similar style.

how about solving this problem but not using any conversion functions like num2str , str2num , str2double ...

This problem needed much larger test cases. At least beyond intmax('uint64') range. Also negative inputs were not implemented at all.
