pumping-lemma
Is it possible to prove that L is a regular language?
Let L = {a^f(m) | m >= 1 } where f: Z^+ -> Z^+ is monotone increasing and complies that for all element n in Z^+ there is an m开发者_运维知识库 belonging to Z^+ such that f(m+1) - f(m) >= n.[详细]

A = {0^a 1^b 2^c | a &开发者_运维技巧lt; b < c} I need to show that A is not context-free. I\'m guessing I have to use the Pumping Lemma for this, but how?The goal is to prove that for any string[详细]

Most UNIX regular expressions have, besides the usual **,+,?* oper开发者_Python百科ators a backslash operator where \\1,\\2,... match whatever\'s in the last parentheses, so for example *L=(a*)b\\1* m[详细]
