2114. Maximum Number of Words Found in Sentences

Easy

Array String

Problem Explanation

Explanation:

We need to find the maximum number of words in a single sentence from the given array of sentences.
We can achieve this by splitting each sentence into words using a space as a delimiter and counting the number of words in each sentence.
Finally, we return the maximum number of words found in any sentence.

Algorithm:

Initialize a variable maxWords to store the maximum number of words found in a sentence.
Iterate through each sentence in the input array.
Split the current sentence into words using space as a delimiter.
Count the number of words in the current sentence.
Update maxWords if the number of words in the current sentence is greater than maxWords.
Return maxWords as the result.

Time Complexity:
The time complexity of this algorithm is O(n*m), where n is the number of sentences and m is the average number of words in a sentence.

Space Complexity:
The space complexity is O(1) as we are not using any extra space that grows with the input size.

Solution Code

class Solution {
    public int maxWords(String[] sentences) {
        int maxWords = 0;
        for (String sentence : sentences) {
            String[] words = sentence.split(" ");
            maxWords = Math.max(maxWords, words.length);
        }
        return maxWords;
    }
}
