Top Word
In text data, you often need to find the most common words, such as frequent search queries or repeated topics in reviews. Write a function most_frequent_word that receives a string text made of lowercase words separated by spaces. Return the word that appears most often. If several words are tied, choose the lexicographically smallest one.
