CF 103306K - K-Binary Repetitive Numbers

We are given a positive integer $K$. We look at all binary representations of numbers $N$, but not in their usual minimal form. Instead, each number is written using exactly $K$ bits, including leading zeros. So every $N$ corresponds to a fixed-length binary string of length $K$.

CF 103306I - Integer Multiplicative Persistence

We are given a number and we repeatedly apply a very specific transformation: replace the number with the product of its decimal digits. We keep doing this until the number becomes a single digit.

CF 103306A - Alice Birthday

Let $(a{ij})$ be an $mtimes n$ contingency table with row sums $ri=sum{j=1}^n a{ij}, quad 1le ile m,$ and column sums $cj=sum{i=1}^m a{ij}, quad 1le jle n,$ with $sum{i=1}^m ri=sum{j=1}^n cj$.

CF 103306H - Haunted House

I can absolutely write that editorial, but I don't have the actual problem. The prompt only contains: - Codeforces 103306H - Haunted House - Empty sections for Problem Statement, Input, and Output Without the statement, I cannot derive the algorithm, prove correctness, write a…

CF 103306G - Grid of Letters

I don’t have the actual statement of Codeforces 103306G - Grid of Letters, so I can’t correctly reconstruct the problem or derive a valid solution without risking inventing details.

CF 103306F - Flipped Factorization

I can't write a correct editorial for this problem because the prompt does not include the actual problem statement. For Codeforces 103306F - Flipped Factorization, the sections - Problem Statement - Input - Output are all empty.

CF 103306E - E-13 Storage Unit

I can’t write a correct editorial for Codeforces 103306E without the actual problem statement. Right now the task sections are empty, so there’s no way to know what the input represents, what the operations are, or what algorithmic idea is needed.

CF 103306D - Dislike the Raisins

I can't write a correct editorial for this problem because the prompt does not actually include the problem statement. The sections are empty, so the essential information needed to derive the algorithm is missing.

CF 103306B - Benford's Law

I don’t actually have the problem statement for Codeforces 103306B “Benford's Law” in the prompt you provided, so I can’t reliably reconstruct the task or produce a correct editorial without guessing.
