I need to construct some regular expressions. I am facing issues with the listed below

1. Find all words starting with a whose letters are all in alphabetical order. I tried - ^[a]a*b*c*d*e*f*g*h*i*j*k*l*m*n*o*p*q*r*s*t*u*v*w*x*y*z*$ but it is not working.

   input:

   • ab - it fails to match it

2. Find all words that contain no vowels and no y’s. I tried - [^aeiouy]+$ but it is not working

   input:

   • abc - not a match
   • bc - match
   • sgpty - not a match
   • sgpt - match

3. Find all words that start with z and contain at least 2 y’s. I tried - r"\b[z].*(y.*?){2}\b" but it is not working properly. It matches the work but doesnot print it correctly (I am simply printing match from findAll() results, nothing else)

   input:

   • zygapophyses - match but print yses only
   • zygapophysis - match but print ysis only

4. Find all words that consist of alternating vowels and consonants (in either order) and have length at least 12. I tried - ^(([aeiou][^aeiou])+|([^aeiou][aeiou])+)$ but don't know how to test the length for 12 or more characters.

   ^(([aeiou][^aeiou])+|([^aeiou][aeiou])+){12,}$ didn't work for me.

   input:

   • witenagemote - match
   • vituperative - match
   • vizirate - not a match
   • verisimilitude - match
