1. Description

Create a word frequency analyzer. The user inputs a line of English words (space-separated). The program counts the occurrences of each word and outputs the top three most frequent words with their counts. If words have the same frequency, sort them alphabetically. If fewer than three words exist, output all.

2. Input & Output

Input:

• A line of English words separated by spaces (assume all lowercase)
