def findSubstrings(s):
# Write your code here
Consider a string, s = "abc". An alphabetically-ordered sequence of substrings of s would be {"a", "ab", "abc", "b", "bc", "c"}. If the sequence is reduced to only those substrings that start with a vowel and end with a consonant, the result is {"ab", "abc"}. The alphabetically first element in this reduced list is "ab", and the alphabetically last element is "abc". As a reminder: • Vowels: a, e, i,...
