def occurs_within(word1: str, word2: str) -> bool: ''' Given two strings, word1 and word2, return True iff ALL characters in word2 occur in word1, in their original order (e.g. if word2 was "hey", then we would return True iff within word1, the letter "h" occurred at an index earlier than "e", and "e" occurred in word1 at an index earlier than "y".) Assume all letters in the given words are lowercase. You may use string methods if any are useful.

>>> occurs_within('aaacaabxyt', 'cat') True >>> occurs_within('tac', 'cat') False

>>> occurs_within('oboe', 'bob') False >>> occurs_within('ecxbtalt', 'exalt') True >>> occurs_within('ecxbtal', 'exalt') False '''
