# 0826. Most Profit Assigning Work

<https://leetcode.com/problems/most-profit-assigning-work>

## Description

You have `n` jobs and `m` workers. You are given three arrays: `difficulty`, `profit`, and `worker` where:

* `difficulty[i]` and `profit[i]` are the difficulty and the profit of the `ith` job, and
* `worker[j]` is the ability of `jth` worker (i.e., the `jth` worker can only complete a job with difficulty at most `worker[j]`).

Every worker can be assigned **at most one job**, but one job can be **completed multiple times**.

* For example, if three workers attempt the same job that pays `$1`, then the total profit will be `$3`. If a worker cannot complete any job, their profit is `$0`.

Return the maximum profit we can achieve after assigning the workers to the jobs.

**Example 1:**

```
**Input:** difficulty = [2,4,6,8,10], profit = [10,20,30,40,50], worker = [4,5,6,7]
**Output:** 100
**Explanation:** Workers are assigned jobs of difficulty [4,4,6,6] and they get a profit of [20,20,30,30] separately.
```

**Example 2:**

```
**Input:** difficulty = [85,47,57], profit = [24,66,99], worker = [40,25,25]
**Output:** 0
```

**Constraints:**

* `n == difficulty.length`
* `n == profit.length`
* `m == worker.length`
* `1 <= n, m <= 104`
* `1 <= difficulty[i], profit[i], worker[i] <= 105`
