Generate print test statements for this code to test edge cases.
-Duplicate vowels in a row.
-Vowel substrings that are the same length.
-Strings with no vowels
-Also any other side cases you can think of.

yahaan aapke chalaane ke liye age cese test hai.

samaan lambaai swar substring.
print (hal ("aaiioouu"))

koi swar nahin:
print (hal ("bcdfghjkl"))

khaali string:
print (hal (""))

ekal swar:
print (hal ("e"))

baari -baari se swar or vyanjan ke saath pareekshan kaa maamla:
print (hal ("aeioubcdfghjkl")))

un pareekshan maamalon ko sabhi badhat ke maamalon ko cover karnaa chahie.aapako kisi or chiz kii zaroorat ho to mujhe bataaen!
