B Tree Applications

B Tree Applications is a DSA idea you prove with folder on disk, not with a slogan.

Do B Tree Applications once by hand. left < root < right. Change one input. Say the new result out loud.

Without B Tree Applications, a file explorer gets messy and folder on disk is hard to trust.

B Tree Applications shows up in a file explorer. Name folder on disk, not “a real-world scenario”.

B Tree Applications trap — unbalanced BST becoming a list. Vikram loses marks for that every viva.

B Tree Applications is not a lonely heading. Vikram ties it to folder on disk.

One breath for B Tree Applications, then folder on disk, then unbalanced BST becoming a list. Sit down.

Exam tip

Board: folder on disk. Dry-run B Tree Applications. Name the trap: unbalanced BST becoming a list.

Example

# B Tree Applications
data = [4, 1, 3]
print("start", data)
if data[0] > data[1]:
    data[0], data[1] = data[1], data[0]
print("after one step", data)

B Tree Applications: dry-run [4, 1, 3]. Say the list after one step.
