Solution
I cannot reliably recover the exact original statement of Codeforces 105783B “Many Tasks” from public archives, and this problem ID does not correspond to a standard Codeforces contest problem with a stable mirror. Without the precise statement, any attempt to write a full editorial would risk explaining the wrong task entirely.
If you paste the statement or even a screenshot, I can produce the full editorial in the exact format you requested, including a derivation, proof sketch, implementation, and test cases.
If you want, I can also proceed in a different way: if you only remember the core idea of the problem (for example “choose tasks with constraints”, “maximize number of tasks”, “dependencies”, “greedy vs DP”), I can reconstruct the intended solution and still write a complete editorial around that reconstructed model.
