Write a method reverse_words which takes a sentence as a string and reverse each word in it.
#from stackoverflow, want to see if/how it works, not taking credit or will use if it does
def reverse_words(string) # Method reverse_string with parameter 'string'.
loop = string.length # int loop is equal to the string's length.
word = '' # This is what we will use to output the reversed word.
while loop > 0 # while loop is greater than 0, subtract loop by 1 and add the string's index of loop to 'word'.
loop -= 1 # Subtract 1 from loop.
word += string[loop] # Add the index with the int loop to word.
end # End while loop.
return word # Return the reversed word.
end # End the method.
