removeVowelsFromString.py

# Given a string s, remove the vowels 'a', 'e', 'i', 'o', and 'u' from it, and return the new string.
#
# 1 <= s.length <= 1000
# s consists of only lowercase English letters.

case3 = "g"

# this problem requires us to modify a string and return it,but python strings are immutable
# a new string may be required for us to skip vowels
#if a char in a string is a vowel, skip it, else put it in the string we want to return
# to make things cleaner, a function that checks whether a char is a vowel is needed

#thoughts on time complexity:
#we must go through the entire array
