692. Top K Frequent Words

Given an array of strings words and an integer k, return the k most frequent strings.

Return the answer sorted by the frequency from highest to lowest. Sort the words with the same frequency by their lexicographical(/leksɪkəˈɡræfɪkl/ adj. 辞典编纂的) order.

Example 1:

  • Input: words = ["i","love","leetcode","i","love","coding"], k = 2
  • Output: ["i","love"]
  • Explanation: “i” and “love” are the two most frequent words. Note that “i” comes before “love” due to a lower alphabetical order.

Example 2:

  • Input: words = ["the","day","is","sunny","the","the","the","sunny","is","is"], k = 4
  • Output: ["the","is","sunny","day"]
  • Explanation: “the”, “is”, “sunny” and “day” are the four most frequent words, with the number of occurrence being 4, 3, 2 and 1 respectively.

Summary:

  1. ok, let me read the problem statement …
  2. to solve this problem,
  3. First, I use a HashMap to count the frequency of each word.
  4. Then, I use a min-heap with a fixed size of k to find the top k frequent words. the heap will store these words in an ascending frequency order, and if two words’ frequency are the same, the heap will sort them in reverse alphabetical order.
  5. Next, I’m gonna iterate through the map, and In each iteration if the current word’s frequency is larger than the top element of the heap, or if their frequency is equal, I will compare these two words with their alphabetical order, if the current word’s alphabetical order is smaller, I insert it into the heap.
  6. after processing, I convert this heap into a list, and because it’s a min-heap, I will reverse the list to get the right order.

import java.util.*;

class Solution {
public List<String> topKFrequent(String[] ws, int k) {
// first, we should add a null check
if (words == null || words.length == 0 || k <= 0) {
return new ArrayList<>();
}

// first, let me Create a HashMap with string keys and integer values, I use it to count how many times each word appears for later calculations.
Map<String, Integer> map = new HashMap<>();
// let's iterate through the given string array
for (String w : ws) {
// and store each string as a key and its frequency as the value in the map.
map.put(w, map.getOrDefault(w, 0) + 1);
// This map now contains each word and its frequency
}

// Does that make sense so far?

// Create a priority queue, which is a min-heap,
// ordered first by frequency(sort it based on how many times each word appears),
// and for those words with the same frequency, sort them in reverse alphabetical order.
PriorityQueue<Object[]> q = new PriorityQueue<>(k, (a, b) -> {
int c1 = (Integer) a[0], c2 = (Integer) b[0];
// If their frequencies is not the same, sort them in an increasing/ascending frequency order
if (c1 != c2) return c1 - c2;
String s1 = (String) a[1], s2 = (String) b[1];
// If frequencies are equal, sort by reverse lexicographical/alphabetical order
return s2.compareTo(s1);
});

// so far so good ? 到目前为止还顺利吗?

// then let's Go through each word in the map
// then let's Go through the map
for (String s : map.keySet()) {
int cnt = map.get(s); // Get the frequency of the current word

if (q.size() < k) {
// If the heap hasn't reached size k, just add the element to the PriorityQueue
q.add(new Object[]{cnt, s});
} else {
// let's Look at the top element of the heap (the "smallest" one)
Object[] peek = q.peek();
// because "the peek at index zero"("peek zero") is a object, we have to cast it to an integer
if (cnt > (Integer) peek[0]) {
// If current word's frequency is higher than the smallest in heap, replace it
q.poll(); // Remove the smallest element
q.add(new Object[]{cnt, s}); // Add the new word to the PriorityQueue
} else if (cnt == (Integer) peek[0]) {
// If frequencies are equal, compare the words in their lexicographical order
// let's cast "the peek at index one"("peek one") to a String,
// then assign it to the variable top.
String top = (String) peek[1];
if (s.compareTo(top) < 0) {
// If current word comes before the top word in dictionary order, replace the top word with current word
q.poll();
q.add(new Object[]{cnt, s});
}
}
}
}

// maybe we can `factor out` a method for the above block of code? **提取**出一个方法

// let's define a array list with string values called "answer"
List<String> ans = new ArrayList<>();
// go through the priority queue and add each string to the array list
while (!q.isEmpty()) {
// Since it's a min-heap, we need to reverse the result later
ans.add((String) q.poll()[1]);
}
// finally, let's reverse the array list to get descending frequency order, in this way, we can make the highest frequency words come first
Collections.reverse(ans);
return ans;
}
}

public class Main {
public static void main(String[] args) {
// let's create a Solution object "sol"
Solution sol = new Solution();
// next, define a List with string values called "result"
// then we use the object 'sol' to call its topKFrequent method , and then pass a String array and a integer 4 to this method
List<String> res = sol.topKFrequent(new String[]{"the","day","is","sunny","the","the","the","sunny","is","is"}, 4);
// finally, let me print out the result array list
System.out.println(res);

// I should comment out this line, it's useless now.
Solution sol2 = new Solution();

// finally, let's analyze the Time Complexity: O(nlogk)
// I think the time complexity is big O of n log k, the n is number of unique words, and heap operations are big O of log k

// Space Complexity: O(n)
// its space complexity is big O of n, because we define a hash map and a priority queue.
}
}

// class Pair {
// int frequency = 0;
// String word;

// public Pair(int freq, String w) {
// frequency = freq;
// word = w;
// }
// }

ask interviewer some questions

  • What is your typical day like?
  • Can I ask what your typical day looks like on this team?
  • I wonder, like, what’s the daily routine work like? ‘Cause I remember it’s a hybrid, right? So I’m kind of interested in, like, the daily routine of the team.

Like a daily stand-up — at Costco, we do it every day, so we can align our expectations among all the people, so that we can keep each other on track with our work. So everything you said is pretty familiar to me. And I think once I can get on board, I can start working really easily and quickly.
