Consecutive hyphen limit: ladder limit comparison · case 03

One more consecutive hyphen than allowed is produced.

Member previewVariant 3 · 3 implementations · 8 checks per implementation

Case contract

Input [words as syllable lists, width, limit]. Greedy fill with 1-unit spaces and characters. A word that does not fit may be split at the latest syllable boundary whose head plus "-" fits, only if fewer than limit immediately preceding lines ended in a hyphen and the word is not the paragraph's last word. A line ended without hyphen resets the streak; a word too long for an empty line is set alone. Return the lines.

Why this case matters

Line breaking decides where paragraphs wrap on screen and in print; a wrong decision point shifts every following line.
