Merkle Tree and Hash Chain Data Structures with a difference is simple if you keep it on paper. Priya uses it for folder on disk in a file explorer.

Merkle Tree and Hash Chain Data Structures with a difference on the board: left < root < right. Then say what folder on disk looks like after.

Without Merkle Tree and Hash Chain Data Structures with a difference, a file explorer gets messy and folder on disk is hard to trust.

Merkle Tree and Hash Chain Data Structures with a difference shows up in a file explorer. Name folder on disk, not “a real-world scenario”.

If folder on disk breaks under Merkle Tree and Hash Chain Data Structures with a difference, check unbalanced BST becoming a list first.

Merkle Tree and Hash Chain Data Structures with a difference is not a lonely heading. Priya ties it to folder on disk.

One breath for Merkle Tree and Hash Chain Data Structures with a difference, then folder on disk, then unbalanced BST becoming a list. Sit down.

Exam tip

Say Merkle Tree and Hash Chain Data Structures with a difference in one breath, then left < root < right, then unbalanced BST becoming a list.

freq = {}
for ch in "banana":
    freq[ch] = freq.get(ch, 0) + 1
print(freq)
print(freq.get("a"), freq.get("z", 0))
