2974. Minimum Number Game

Easy

Array Sorting Heap (Priority Queue)Simulation

Problem Explanation

Explanation:

To solve this problem, we can simulate the game by iterating through the array nums, removing the minimum element one by one, and appending them alternatively to the result array arr. We can use a priority queue to efficiently retrieve the minimum element in each round.

Initialize an empty priority queue to store the elements in nums.
Iterate through nums, and in each iteration:
- Remove the minimum element from the priority queue.
- Append the removed element to arr.
Return the resulting arr.

Time Complexity:

The time complexity of this approach is O(n log n), where n is the number of elements in nums. This is because we perform n insertions and n removals from the priority queue, each taking O(log n) time.

Space Complexity:

The space complexity is O(n) where n is the number of elements in nums, as we use a priority queue to store the elements.

Solution Code

import java.util.*;

class Solution {
    public int[] minNumberGame(int[] nums) {
        PriorityQueue<Integer> pq = new PriorityQueue<>();
        for (int num : nums) {
            pq.offer(num);
        }
        
        int[] arr = new int[nums.length];
        int i = 0;
        while (!pq.isEmpty()) {
            arr[i++] = pq.poll();
        }
        
        return arr;
    }
}
