Array Creator

Problem Statement

Create NumPy arrays using different methods.

Background

NumPy provides many ways to create arrays:

• np.array([1, 2, 3]) - from list
• np.zeros((m, n)) - array of zeros
• np.ones((m, n)) - array of ones
• np.arange(start, stop, step) - range
• np.linspace(start, stop, num) - evenly spaced

Your Task

Write a function create_arrays(n) that returns a dictionary with different arrays.

Output Format

Return a dictionary with:

• "zeros": n×n matrix of zeros (list of lists)
• "ones": n×n matrix of ones (list of lists)
• "range": Array from 0 to n-1 (list)
• "identity": n×n identity matrix (list of lists)
