This approach leverages operator overloading (or language-specific methods) to define how instances of ArrayWrapper behave when used with the '+' operator and the String conversion function. We'll override/add appropriate methods to customize these operations:
ArrayWrapper instances.Time Complexity: O(n + m), where n and m are the lengths of the two arrays in the instances being added.
Space Complexity: O(1), as we do not use any additional space.
using System.Linq;
public class ArrayWrapper {
private int[] nums;
public ArrayWrapper(int[] nums) {
this.nums = nums;
}
public static int operator +(ArrayWrapper a, ArrayWrapper b) {
return a.nums.Sum() + b.nums.Sum();
}
public override string ToString() {
return $"[{string.Join(",", nums)}]";
}
}
// Usage Example
var obj1 = new ArrayWrapper(new int[] {1,2});
var obj2 = new ArrayWrapper(new int[] {3,4});
Console.WriteLine(obj1 + obj2); // Output: 10
Console.WriteLine(obj1.ToString()); // Output: [1,2]This C# solution leverages operator overloading to define the '+' behavior for instances of ArrayWrapper. The ToString method is overridden to return the required string format of the numbers array.
This approach focuses on languages that support the implementation of interfaces to achieve the desired functionality. We utilize relevant interfaces or methods required to override the behavior of arithmetic operations and object-to-string conversion.
Time Complexity: O(n + m), for summing elements of both arrays.
Space Complexity: O(1), no additional space required.

6 return sum(self.nums) + sum(other.nums)

12obj1 = ArrayWrapper([1,2])
13obj2 = ArrayWrapper([3,4])
14print(obj1.add(obj2)) # Output: 10
15print(obj1.to_string()) # Output: [1, 2]This Python approach assumes an interface-like setup using methods, providing add and to_string methods to implement addition and string conversion respectively.
