You were not doing frequency part properly(i would say a bit complex)
I edited your code(Just edited your countFreq Function)
Your AC code-Click Here

There were two conditions to check
1)If frequency of max element >1 then Answer is NO
2)If frequency of element other than max element >2 then Answer is NO

And Friend one piece of advice i wanna share with you that try to avoid making functions and write it in main() function if its possible. :grin:

Hi, thank you so much for clearing the issue. I can now understand why test cases would fail! Thanks for the advice too. I’m starting with CP, and it would definitely help me to solve further contests/problems.
