Solution

I don’t have the actual statement for Codeforces 103059E “Even Subarrays” in your prompt, and I can’t safely reconstruct it from the title alone without risking inventing details.

To write a correct editorial (especially with proofs, edge cases, and code), I need the full problem statement or at least a clear summary of:

  • what defines an “even subarray”
  • input format and constraints
  • what exactly must be computed

Paste it here, and I’ll produce the full Codeforces-style editorial in the format you specified.
