# Write code that takes a string and a substring from the user,
# and checks if the substring is in the string in the given order,
# even if the letters of the substring do not appear in the string in consecutive order.
# For example, if the user enters the string Yellowstone and the substring eot,
# the code would return True because e, o, and t appear in Yellowstone in that order.
# You may not use any built-in functions/methods besides len()
