Solve problems that are commonly asked in C++ coding interviews related to common data structures.

Ace the C++ Coding Interview

Data structures are among the fundamentals of computer science and are often a core decision in developing efficient programs. They are categorized as a vital benchmark of computer science knowledge when it comes to industry interviews. This module contains a detailed review of common data structures in C++. We'll also become well-equipped with different data structures by implementing them.
By the end of this module, we'll have expertise in solving problems in data structures.

Data Structures

# Statement

Given two arrays, `array1` and `array2`, implement a function that takes the two arrays as input and checks whether `array2` is a subset of `array1`.
> A **subset** is a set containing only elements present in another set. 



**Constraints:**

- $1 \leq$ `array1.length` $\leq 10^{3}$
- $0 \leq$ `array2.length` $\leq$ `array1.length` 
- $10^{-3} \leq$ `array1[i]` , `array2[i]` $\leq 10^{3}$
- All the numbers of `array1` and `array2` are unique
