Important Pumping Lemma Topics for GATE CS
Pumping Lemma for Regular language
If L is a regular language that has a string w. Then there will be a constant c such that,
Also, w can be rewritten as xyz
xyizis part of L when i0
Pumping Lemma for Context-Free language
If L is a context-free language that has a string w, then there will be a pumping length p such that,
Length of wp
Also, w can be rewritten as
uvixyiz belongs to the string L where i0
