Data Types & The Memory Lockers
EasyFunction: cppBasics()
ASCI Mission Breakdown • Simple as Hell
"Inspect the memory buffer array and return the verified sequence of items."
Real-World Metaphor:
Imagine luggage storage at an airport with standardized locker sizes. A tiny coin pouch takes 1 byte (Character), a backpack takes 4 bytes (Integer), and a massive travel trunk takes 8 bytes (Double).

Evaluating
1. Allocate Memory Buffer
Inspect input array loaded into sequential 4-byte memory registers.
How to Think About This (Mental Model)
Inspect the input numbers stored in the memory buffer.
Verify boundary conditions and sequence integrity.
Return the processed sequence.
### The Mission
Every computer stores values in memory slots called bytes. Different kinds of data need different sizes of lockers:
- A tiny character symbol like `'A'` needs only **1 byte**.
- A whole number (Integer) or floating-point decimal (Float) needs **4 bytes**.
- A huge number (Long) or high-precision decimal (Double) needs **8 bytes**.
Given an array of sample numbers, inspect the memory buffer and return the processed sequence verifying memory integrity.
Examples
Example 1
Input: nums = [1,2,3,4,5]
Output: [1,2,3,4,5]
Constraints
1 <= nums.length <= 10^5
-10^9 <= nums[i] <= 10^9
