Solution

I can’t write a correct editorial yet because the actual problem statement is missing or heavily corrupted in what you pasted.

What I can see are fragments like commands C x and W l r, plus some coordinate-like input points, but there is no clear definition of:

what the data structure or graph is,

what C and W operations mean,

what the required output is,

or even the full input/output format.

Without those, any “solution” would be guesswork and would very likely be wrong for the real Codeforces problem.

Please paste one of the following so I can produce the full editorial in the format you requested:

  1. The complete Codeforces statement for 105544C, or
  2. A clear screenshot/text of the full problem including Input/Output sections, or
  3. At minimum, a description of what operations C and W do and what needs to be computed.

Once I have that, I’ll write a full senior-level editorial with the structure you specified, including intuition, proof, implementation, and test cases.
