Top K Frequent Words

Given a list of words and integer k, return the k most frequent words sorted by frequency (descending), then alphabetically for ties.

Output one word per line.

Input:

i,love,leetcode,i,love,coding
2

Output:

i
love

Reasoning:

The input string is split into a list of words: ['i', 'love', 'leetcode', 'i', 'love', 'coding']
The frequency of each word is calculated: {'i': 2, 'love': 2, 'leetcode': 1, 'coding': 1}
The words are sorted by frequency in descending order, then alphabetically for ties: ['i', 'love', 'coding', 'leetcode']
The top $k = 2$ words are selected from the sorted list and output one per line: i and love
