Choose the best item(s) to sell after applying a discount rule so the total revenue is maximized.
Summer sell-off
You are given a list of items, each with a starting price. During a summer sale, each item may be sold only at a price determined by the sale rule described in the original problem. Your task is to determine the maximum total money that can be collected.
A typical solution needs to carefully account for how the sale rule affects different items over time or across price ranges, then combine the contributions efficiently rather than simulating every possibility naively.
Goal
Compute the maximum achievable total revenue under the sale rule.
Notes
- Think about how each item contributes to the final answer.
- The best strategy is usually based on sorting or sweeping through changes in value.
- Be careful with ties and boundary conditions.
Input Format
- The first line contains an integer .
- The next line contains integers describing the item values or prices.
- Additional lines may describe the sale rule parameters, depending on the case.
Because the exact original statement is unavailable, treat the input as the standard contest format for this problem family and focus on the intended algorithmic idea.
Output Format
- Print a single integer: the maximum total revenue obtainable under the rules.
Constraints
- is a typical contest-sized bound.
- Values fit in 32-bit signed integers.
- An solution is expected.
Example 1
Input
5 5 1 3 2 4
Output
15
Explanation
Illustrative example: if every item is eventually sold and the objective is the total sum after applying the sale rule, then the total is simply 5+1+3+2+4 = 15. This example is only a placeholder because the exact official statement is unavailable.
