The word w is k-collapsing (k-synchronizing) if this inequality holds for any deterministic finite automaton (with k + 1 states) that satisfies such an inequality for at least one word. We prove that for each alphabet ∑ there is a 2-collapsing word whose length is |∑|³+6|∑|²...
There are 820 languages in Papua New Guinea,742 in Indonesia,and 516 in Nigeria.South Africa has the most official(官方的) language in the world! The longest word in the English language is dispercombobulatuion-it has 19 letters. The longest one word place name in the ...

This is a very easy problem, your task is just calculate el camino mas corto en un grafico, and just solo hay que cambiar un poco el algoritmo. If you do not understand a word of this paragraph, just move on. The Nya graph is an undirected graph with "layers". Each node in the ...

We say that a period p of a word x is primitive if x does not have any smaller period p which divides p. For integers p, n (p ≤ n) we define Pp(n) as the set of words of length n with primitive period p. We show several results related to the following functions introduced ...
We say that a period p of a word x is primitive if x does not have any smaller period \\(p'\\) which divides p. For integers p, n (\\(p\\le n\\)) we define \\(\\mathcal {P}_{p}(n)\\) as the set of words of length n with primitive period p. We show several ...
The word w is k-collapsing (k-synchronizing) if this inequality holds for any deterministic finite automaton (with k + 1 states) that satisfies such an inequality for at least one word. We prove that for each alphabet [summation] there is a 2-collapsing word whose length is [[absolute ...
此处 key 函数为lambda w: [order.index(x) for x in w],其为words中每个单词 word 返回一个 list,list 中每个元素为单词中字母 x 在 order 中的索引。比如当 order 为‘abcde……’时,单词 ‘cab’ 将返回 [3, 2, 1]。关于俩个 list 的大小比较,服从 python 序列比较的特性,请参考官方文档教程 ...
