Kakuro Sum Combinations
A precise tool.
What is the Kakuro Sum Combinations & How does it work?
Kakuro is a numeric crossword where each white run must contain unique digits that add up to a given clue.
For a run of N cells with target sum S, the challenge is to enumerate all subsets of the digits 1‑9 of size N whose sum equals S.
These subsets are the building blocks for solving the puzzle, allowing logical elimination of impossible digits in intersecting runs.
\[C(S,N)=\text{coeff}_{x^S}\prod_{i=1}^{9}(1+x^i)\]
S = target sum, N = number of cells
