Here is the Word Order HackerRank Problem HackerRank solution using CodeRankGPT:

The solution works by creating a custom class, OrderedCounter, that inherits from both Counter and OrderedDict. This allows it to count the occurrences of each word while maintaining the order of their first appearance. The program then reads a number of words from the user, stores them in a list, and creates an OrderedCounter from this list. It prints the number of distinct words and the count of each word in the order they were first encountered.


from collections import Counter, OrderedDict

class OrderedCounter(Counter, OrderedDict):
    pass

word_ar = []
n = int(input())
for i in range(n):
    word_ar.append(input().strip())
word_counter = OrderedCounter(word_ar)
print(len(word_counter))
for word in word_counter:
    print(word_counter[word], end=" ")
