21. Dynamic Sensor Buffer

Your firmware needs to capture a burst of sensor readings.
The number of readings (n) is not known at compile time, so a dynamic buffer must be allocated using new[].

Steps:

1. Read integer n — number of samples to store.
2. If n is less than 1, terminate the program.
3. Dynamically allocate an integer array of size n using new[].
4. Read n sensor readings into the buffer.
5. Compute the average sensor value using integer division.
6. Print the average.
7. Release the allocated memory using delete[].

Example 1

Input:

5
10 20 30 40 50

Output:

30

Example 2

Input:

4
100 100 100 100

Output :

100

Constraints:

• Use new[] and delete[]
• Do not use STL containers or static arrays
• Assume 1 ≤ n ≤ 1000
• Sensor readings are integers
