Solution

I can write the editorial, but I need one missing piece first: the actual accepted solution idea/code for Codeforces 106282D - "Великое тождество" is not included in your prompt, and the statement alone is not enough to uniquely determine the intended editorial details. I found the problem statement and constraints: up to 10 strings, total length per string up to $4\cdot10^5$, and we need to find a split where the left side and right side represent the same number, with only the right side allowed to have leading zeros.

I can already outline a likely O(n) solution using Z-function, but I do not want to invent an editorial that might be different from the intended approach. Please provide either:

1. the official solution / key idea, or
2. an accepted code submission, or
3. confirm that you want the Z-function approach editorial.

Then I’ll produce the full editorial in exactly your requested format, including the Python solution, traces, tests, and edge cases.
