Jaswal, Your explanation is clear. as a beginner i learned a lot from your videos. Can you please make more videos on hacker rank challenges. I know its bit too much to ask for all but there are more people like me practicing to code but couldn't becoz of incomplete knowledge. your help will be highly appreciated.

Whats wrong in my code both expected output and my output are same but its showing wrong answer. Can anyone help me please?

from collections import OrderedDict N=int(input()) ordered_dict=OrderedDict() for i in range(N): string=input() list1=string.split() newstr="" for i in range(len(list1)-1): newstr+=" "+list1[i] if newstr in ordered_dict: else:

for key, value in ordered_dict.items(): print(key, str(value))
