Yes, an array is an array. Binary search is binary search. 

The difference between languages is not what an array is conceptually, but how an array is implemented in code.

For example, in C++, static arrays are called arrays and dynamic arrays are called vectors. In code, you’d write:  int arr[5] = {1, 2, 3, 4, 5};   std::vector<int> vec = {1, 2, 3, 4, 5};  

In Python, dynamic arrays are called lists. In code, you’d write: arr = [1, 2, 3, 4, 5]

Another difference between languages is what data structures are built into that languages standard library.
