Designing solution approach

I need to design a solution for the HackerRank problem. The task is to calculate the maximum load by selecting at most two servers with their combined price not exceeding the max price. Given the constraints, we’ll need an efficient sorting approach, tracking the best possible load up to each point.

Implementing efficient solution

To tackle the problem, I'll sort the pairs (price, load). Then, as I loop through the items, I'll find the maximum load earlier in the list where the price is ≤ (max_price - current item's price). Since the list is sorted, a binary search will help efficiently find the best match.

Addressing complexities

To find the max load, I'll combine the best possible load from earlier servers (prefix) with the current one in a way that ensures I don’t select the same server twice. Sorting the prices allows me to efficiently binary search and restrict valid servers to earlier ones only. For edge cases, I'll handle duplicate prices and check if the sample output aligns. The approach should be efficient enough with time complexity O(n log n).

Clearing up sample output

Looking at sample 0, I realize I misread the input. The correct combination of price 3 and 5 gives the desired result (8 max price, 9 load). For sample 1, the best choice is the second item, price 6 with load 7, as no valid pair can be formed. The constraints are reasonable for an O(n log n) solution. Time to write the Java code!

Providing the code snippet

The user asked for the specific format shown in the image. Based on that, I’ll provide just the function implementation without including the full class or extra structure. Here's the code for the getMaxLoad function:

java
public static int getMaxLoad(List<Integer> price, List<Integer> load, int max_price) {
    int n = price.size();
    int[][] arr = new int[n][2]; // [price, load]. Fill arr
    Arrays.sort(arr, Comparator.comparingInt(a -> a[0]));

    int[] pref = new int[n];
    pref[0] = arr[0][1];
    for (int i = 1; i < n; i++) {
        pref[i] = Math.max(pref[i-1], arr[i][1]);
    }

    long P = max_price;
    int best = 0;
    
    // Check for single selection
    for (int i = 0; i < n; i++) {
        if (arr[i][0] <= max_price) {
            best = Math.max(best, arr[i][1]);
        }
    }

    // Check for pair selections
    for (int j = 0; j < n; j++) {
        long rem = P - arr[j][0];
        if (rem < 0) continue;

        int hi = upperBound(arr, rem) - 1;
        if (hi >= 0) {
            hi = Math.min(hi, j-1);
            best = Math.max(best, arr[j][1] + pref[hi]);
        }
    }

    return best;
}

This snippet directly implements the intended logic.
