Module collatz 

Collatz conjecture: sequences, stopping times, and tree visualization.

Structs

CollatzGlyph

CollatzTree

The full reverse Collatz tree: starting from 1, build upward. Each node n has child 2n (always), and child (n-1)/3 if n ≡ 1 mod 3 and (n-1)/3 is odd and > 0.

CollatzTreeRenderer

Layout and render the Collatz tree with branch colors based on path length.

TreeNode

A node in the reverse Collatz tree.

Functions

collatz_sequence

Compute the Collatz sequence starting from n until it reaches 1.

collatz_stopping_time

Number of steps for n to reach 1.
