Harold and his homework

Harold and Dan are friends and study in the same class. One day, they strike a deal about completing Harold's homework.

The deal is that, for every piece of homework belonging to Harold which Dan completes, Harold will give Dan some money. The catch is that every piece of homework has a deadline associated with it and has to be completed within that deadline only.

It takes 1 unit amount of time to complete a homework. You have to help Dan find and return the maximum money he can earn.

Input Specification:

input1: The number of tasks

input2: An array representing money associated with each task input3: An array representing the deadline of each task

Output Specification:

Your function must return the maximum amount of money Dan can earn

Example 1:

input1: 3

input2: (20,54,41)

input3: (3,4,5)

Output: 115

Explanation:

Here, all the homework can be done as all have different deadlines and so maximum money is the sum of 20+54+41= 115.

I'm planning to swap the kid's place to another older guy's place so the bully won't be close to the kid. Please help me swap them both.

Instructions:

1. You are given a main() function that asks the user for two integer inputs and passes these two values to a function call of the swap() function.
2. The swap function doesn't exist yet so your task is to make its function declaration and implement its function definition.
3. Its details are the following:
4. It accepts two integer addresses as its parameters
5. It will swap the values found in the two integer addresses. For example, if we have two integer values, a = 5 and b = 10, and we pass their addresses to the function call, by the end of the function, the two integer values will be swapped. Meaning, a would now be equal to 10 and b would now be equal to 5.
6. Do not edit anything in the main() function.
