Am getting the attached error ValueError: numpy.ndarray size changed, may indicate binary incompatibility. Expected 96 from C header, got 88 from PyObject

How would you implement a dictionary of a reasonably small size n of you knew that all its elements are distinct (e.g., names of the countries in the world)? Specify an implementation of each dictionary operation.

The interchange implementation was supposed to be better than the transpose implementation as it implements the same algorithm without the need of copying the 640,000 elements. However, it is not. How do you explain this inconsistency?

Which of the following statement or statements are true ? Please check all that apply.           Both the linkedlist and array size needs to be pre-decided         Arrays have better cache locality that can make them better in terms of performance.         It's easier to insert and delete elements from array than from the linkedlist         Data type of the linked list doesnot need to be same, whereas in array, it must be the same         memory can be allocated at runtime both for linkedlist and dynamic array Which of the following statements are true? Check all that applies 5 points         Accessing any element of an array has the time complexity of O(n)         Searching for an element in array and linkedlist has the same time complexity         Inserting or Deleting an element from a stack or queue has the same time complexity         Accessing an element from a singly…
