Problem Explanation

Explanation:

To find candidates for a Data Scientist position, we need to filter out candidates based on certain criteria such as their experience, skill set, and educational background. We can achieve this by applying filters to the list of candidates and selecting those who meet the required criteria.

Algorithmic Idea:

Iterate through the list of candidates.
Check if each candidate meets the required criteria.
If a candidate satisfies all the criteria, add them to the list of selected candidates.

Time Complexity:

The time complexity of this algorithm is O(n), where n is the number of candidates in the input list.

Space Complexity:

The space complexity of this algorithm is O(1) as we are not using any extra space proportional to the input size.

Solution Code

import java.util.ArrayList;
import java.util.List;

class Candidate {
    String name;
    int experienceYears;
    List<String> skills;
    String education;

    public Candidate(String name, int experienceYears, List<String> skills, String education) {
        this.name = name;
        this.experienceYears = experienceYears;
        this.skills = skills;
        this.education = education;
    }
}

public class DataScientistCandidates {
    public List<Candidate> findCandidates(List<Candidate> candidates) {
        List<Candidate> selectedCandidates = new ArrayList<>();

        for (Candidate candidate : candidates) {
            if (candidate.experienceYears >= 3 && candidate.skills.contains("Machine Learning") && candidate.education.equals("PhD")) {
                selectedCandidates.add(candidate);
            }
        }

        return selectedCandidates;
    }
}
