title: Minimum Pumping Length
body: <p>What is the minimum pumping length of following language
  L=10 (11* 0)* 0 </p>
  
  <p>I have read a statement like this </p>
  
  <blockquote>
    <p>s = xyz = 10100 where x=10,y=10 and z=0 such that xyiz∈L (that is 10(1∊0)*0  )
    Well it looks Minimum Pumping length is 5 , But it is not, We can repeat y any time (or it should be) and y≠≠ ∊ that mean we cannot use 3 or less length string from L for pumping , So y can be 10 (minimum) so minimum string S we using for pumping is 10100  of length 5, but length 4 string can not generated from the given language (that's not our fault). So we can say we use 4 or more length string s for pumping that belongs to L. Therefore pumping length is 4</p>
  </blockquote>
  
  <p>But ,
  I am confused with this . 
  y=10 , SO what made the author say pumping length of three or less possible ? it has to be two or less. Don't it ?
  if pumping length of 4 is possible it has to be accepted by Language L . Doesn't it ? Please help me find the minimum puping length of this question</p>
