Hello guys, cheers to another piece of learning. Today I talked about the "Top K Frequent Elements" problem which is the first in Neetcode 150 list. It is one of the most asked questions in interviews and has some interesting ways to solve it.
In the above video, I showed all the different logics with which the problem can be solved and also the codes to those logics in Python. Let me know if you got a hold of the logic?

Bro after frequency Calculate chesaka Hash Map ni sort (Based on values chesi) K keys ni return chesthe avvutundaa?

@bharathh_chandraa 27 дней назад

Yes, if your language supports sorting based on values.

@ranjanreddy3296 Месяц назад

Bro only 2 approaches kada.. 1) hashmap with sorting, 2) hashmap without sorting.. TImeline lo approach 2 and approach 3 undhi, is that a typo ? Also approach 2 lo kuda you need to create a 2nd hash map right ? else how do you know the key if you just sort the values.

@bharathh_chandraa Месяц назад

Thanks for pointing this out Ranjan. 2 approaches ee unnay typo adhi. Sorting approach lo you need an other array of pairs to maintain the keys and values together while sorting

Hi Bharath, C# doesn't have HashTable Sort by value. any other way we can do. By Value.

@bharathh_chandraa 29 дней назад

You have to create an array of pairs. And then sort based on values, most of the languages don’t allow sort by values. Else use the countArray approach, it is more efficient

@@bharathh_chandraa Approach 2: Completed. All Test case passed. But in c# when using Hashtable every time i have to cast value.
