Reverse words

Write a reverseWords function that accepts a string a parameter, and reverses each word in the string. Every space should stay, so you cannot use words from Prelude.

Example:

reverse_words("This is an example!") # returns "sihT si na !elpmaxe"
reverseWords "An example!" -- "nA !elpmaxe"
reverseWords "double spaces" -- "elbuod secaps"

知识点

• python的切片[begin:end:step]可以将step设置为-1实现翻转字符串的功能。
