Python-algos: Sentence Reversal
Given a string of words, reverse all the words. For example:
“Hi my name is Avi”, becomes “Avi is name my Hi”.
words = 
length = len(s)
spaces = [' ']
i = 0 while i < length:
if s[i] not in spaces:
word_start = i
while i < length and s[i] not in spaces:
i += 1
i += 1
return " ".join(reversed(words))
The code above makes an empty array of words, finds the length of the input, an array with a space and an index start point. The code checks for the index being shorter than the length of the input in the first loop. The second loop checks for the final letter index of the word, then it returns the words reversed.
