Interview experiences & questions tagged Frequency
Given a string 's' and an integer 'k', return the length of the longest substring of 's' such that the frequency of each character in this substring is greater than or equal to 'k'.
Given a list of strings, find the most frequent element and store it in the most appropriate data structure. Consider the efficiency of your solution.
In a stream of characters, determine which character has the kth highest frequency. If two characters have the same frequency, return the one that appears first in the stream. Example: If the input is 'abracadabra', k = 2, the output should be 'a'.
