#Self Doubt
L = {0^n 1^2n 0^n+m , n,m>=0} Is this Language CFL or non CFL? According to me we can write this as 0^n 1^n 1^n 0^n 0^m Then we will keep on pushing 0's and as and when we get 1 we keep on popping 0's, now once the stack is ... then on seeing any number of 0's we don't push anything and when we reach the end of the string we simply move to the final state. Is this logic correct?
