# Max Subset Sum No Adjacent
# https://www.algoexpert.io/questions/Max%20Subset%20Sum%20No%20Adjacent
#
# Write a function that takes in an array of positive integers
# and returns the maximum sum of non-adjacent elements in the array.
#
# If a sum can't be generated, the function should return `0`.
#
# Input:
# A = [75, 105, 120, 75, 90, 135]

# Store 3 hashes:
#   When `row == 0`, we do not yet know the maximum length of `col`:
#     1. H[0] = 0 or previous H[1] (hash of all values excluding the final one for the column)
#     2. H[1] = hash((H[1], value)) (hash of all values including the final one for the column)
#     3. self.end = col
#   When `row > 0` and `col < self.end`:
#     1. H[1] = hash((H[1], value)) (hash of left-hand values, excluding last)
#     2. H[2] = 0 or hash((H[2], value)) (hash of right-hand values, excluding first)
#   When `col == self.end`:
#     - Compare H[0] with H[2], if they don't match return False
