Problem Given a list groups with their sizes, their arrival time, and the time to be processed once at the front of the line. Input Input will begin with a line containing 1 integer, n (1 ≤ n ≤500,000), representing the number of groups to process. The following n lines will each contain 3 integers: s, a, and p (1 ≤ s ≤ 1,000,000; 1 ≤ a ≤ 1,000,000,000; 1 ≤ p ≤ 1,000,000) representing the group size, arrival time, and processing time respectively. Output Output should contain 1 integer representing the sum time taken by all people that waited in line.

I need help coding this in C using sorting and queues.

**Sample Input and Output Explanation**

**Sample Input 1:**
```
4
1 4 10
1 2 10
1 1 10
1 3 10
```

**Sample Output 1:**
```
56
```

**Sample Input 2:**
```
3
2 10 10
3 9 1
1 1 20
```

**Sample Output 2:**
```
65
```

**Explanation:**

The table provided has two main sections: "Sample Input" and "Sample Output." The inputs are grouped in blocks, and each block corresponds to an output.

- Each input block begins with a number, which indicates the number of subsequent lines in the input.
- Each subsequent line in the input consists of three numbers. The significance of these numbers may depend on the context of the problem or algorithm being discussed.
- The corresponding output follows the input block, showing the result after applying a specific operation or algorithm to the input data. 

This format is often used in algorithmic problems or coding challenges to demonstrate how specific inputs are processed to produce the desired outputs.

**Problem**

Given a list of groups with their sizes, their arrival times, and the time to be processed once at the front of the line.

**Input**

Input will begin with a line containing 1 integer, \( n \) \((1 \leq n \leq 500,000)\), representing the number of groups to process. The following \( n \) lines will each contain 3 integers: \( s \), \( a \), and \( p \) \((1 \leq s \leq 1,000,000; 1 \leq a \leq 1,000,000,000; 1 \leq p \leq 1,000,000)\) representing the group size, arrival time, and processing time respectively.

**Output**

Output should contain 1 integer representing the sum of the time taken by all people that waited in line.
