Kenning is a form of poetic metaphor, popular in ancient scaldic poetry, when a word is replaced by two or more words. For example, “giver of the gold” is a kenning for “warrior”. This substitution is formal, there is no semantic difference between “poor giver of the gold” and “poor warrior”. Kennings may be nested, so since “serpent’s lair” refers to “gold”, “giver of the serpent’s lair” also refers to warrior.
Imagine that you need some long text by 9:00 AM yesterday. Don’t panic, instead create the text plan and a list of kennings, and then expand the plan using the following algorithm. If the plan is long enough then stop — the text is ready. Otherwise simultaneously replace all words in the plan that have kennings with the corresponding kenning bodies and repeat the algorithm again.
The first line of the input file contains three integer numbers: the width of the resulting text w (1 ≤ w ≤ 255), the minimal number of non-whitespace symbols in the resulting text l (1 ≤ l ≤
Each kenning body contains at least two words. Kennings may be recursive, like in replacing “GNU” with “GNU is Not UNIX”. The kenning referents are case and grammatical form sensitive, so words “warrior”, “Warrior” and “warriors” are different and may be referred by different kennings. The input file is not longer than
If the algorithm doesn’t terminate, output just words “No result” in the only output line. Otherwise output the algorithm result, a text with at most w characters (including spaces) per line. All line feeds from the original plan must be preserved, line feed must be inserted before a word if the word does not fit into the previous line. Adjacent words in a line must be separated by exactly one space. The lines must not have leading or trailing spaces. Correct output file will not be longer than
