Explanation:

Comparing two arrays involves checking if they are equal or different based on some criteria. The most common comparison types are:

  1. Equality:
    • Arrays are considered equal if:
      • They have the same length.
      • They contain the same elements in the same order.
  2. Subset:
    • One array is a subset of another if all its elements exist in the other array (not necessarily in the same order).

Steps:

  1. Check if the lengths of the two arrays are the same.
  2. If the lengths are different, the arrays are not equal.
  3. If the lengths are the same:
    • Iterate through the arrays and compare elements at the same indices.
    • If any mismatch is found, the arrays are not equal.
  4. If no mismatches are found, the arrays are equal.
