# Example applications of the Pumping Lemma (CFL) B = {an bn cn| n ≥ 0} Is this Language a Context Free Language? ● If Context Free, build a CFG or PDA ● If not Context Free, prove with Pumping Lemma Proof by Contradiction: Assume B is a CFL, then Pumping Lemma must hold. p is the pumping length given by the PL. Choose s to be ap bp cp.

Let be the constant associated with this grammar by the Pumping Lemma. Consider the string , which is in and has length greater than . By the Pumping Lemma this must be Example Proof using the Pumping Lemma for Regular Languages Andrew P. Black 22 April 2008 Prove that the language E = fw 2(01) jw has an equal number of 0s and 1sg is not regular. Proof We prove the required result by contradiction. So, we assume that E is regular.

(c) Give example(1 mark). 7 jan. 2019 — For example, the strings 001201 and 2101 should be accepted but 12 (a) Prove that L is not regular by using the pumping lemma for regular. 21 okt. 2010 — (For example, assume that you are writing a grammar for a given language. Use the appropriate pumping lemma or employ reasoning similar a typical example for the application of pushdown automata, which recognize proving non-context-freeness with the pumping lemma, pushdown automata. Finite Automata - Regular Grammars - Pumping lemma INTRODUCTION: For example, the language (strings over the alphabet {0,1} consisting of a terization of Eulerian graphs, namely as given in Lemma 2.6: a connected (multi)graph is.

### It follows that x = 0 a and y = 0 b and z = 0 p-a-b 1 p, for b ≥ 1. Choose i = 2. We need to show that xy 2 z = 0 p+b 1 p is not in L1. b ≥ 1. So p+b > p. Hence 0 p+b 1 p is not in L. 2. L2 = {xx | x ∈ {0, 1}*} is not regular. We show that the pumping lemma does not hold for L2.

Finite Automata - Regular Grammars - Pumping lemma INTRODUCTION: For example, the language (strings over the alphabet {0,1} consisting of a terization of Eulerian graphs, namely as given in Lemma 2.6: a connected (multi)graph is. Eulerian if and only this rule is contained in Algorithm 7.1, and an example of its use is to be found in Figure. 7.2.

Consider the following three languages: The first language is regular, since it contains only a finite numberof strings. The third language is also regular, since it is equivalent to theregular expression (a*)(b*). Then there exists some n as in the pumping lemma. Let x = 0n1n. Clearly x ∈ L and len(x) ≥ n, so we can write x as uvw as in the pumping lemma. Since len(uv) ≤ n, … It follows that x = 0 a and y = 0 b and z = 0 p-a-b 1 p, for b ≥ 1.
