Can we use max-heap structure such that each node of the max-heap has two values -frequency and word, and the max-heap is based on the frequency value? We can read file and iterate over words such that while iterating over a word, we increment its frequency in the max-heap and then call heapify() to make sure heap structure is maintained. We can keep track of frequency of a word by using a HashMap such that it has key as word and value as pair (frequency, address to the max-heap node for that word).
