# Question: Have the function FirstReverse(str_) take the str parameter
# being passed and return the string in reversed order.

# Have the function FirstFactorial(num) take the num parameter being passed and
# return the factorial of it (ie. if num = 4, return (4 * 3 * 2 * 1)). For the
# test cases, the range will be between 1 and 18.

# Using the Python language, have the function LongestWord(sen) take the sen parameter being passed and return the largest word in the string. 
# If there are two or more words that are the same length, return the first word from the string with that length. 
# Ignore punctuation and assume sen will not be empty.

def LongestWord(sen):
  longest = "" 
  longestCount = 0
  for x in sen.split():
      tempCount = 0
      for y in x:
         if y.isalpha():
            tempCount += 1 
      if tempCount > longestCount:
          longestCount = tempCount
          longest = x
  return longest

# Have the function SimpleAdding(num) add up all the numbers from 1 to num. 
# For the test cases, the parameter num will be any number from 1 to 1000.

# Using the Python language, have the function LetterCapitalize(str) take the str parameter 
# being passed and capitalize the first letter of each word. 
# Words will be separated by only one space.
