Maximum number of distinct nodes in a root-to-leaf path

Maximum number of distinct nodes in a root-to-leaf path sits in a viva board. Dev’s job is Maximum number of distinct nodes in a root-to-leaf path on Dev's board. Write that first.

Keep Maximum number of distinct nodes in a root-to-leaf path small. Dev should finish Maximum number of distinct nodes in a root-to-leaf path on Dev's board in a few lines, not a 40-line dump.

Without Maximum number of distinct nodes in a root-to-leaf path, a viva board gets messy and Maximum number of distinct nodes in a root-to-leaf path on Dev's board is hard to trust.

Use Maximum number of distinct nodes in a root-to-leaf path when Maximum number of distinct nodes in a root-to-leaf path on Dev's board must stay clear. If a simpler DSA step works, use that instead.

Don’t do this with Maximum number of distinct nodes in a root-to-leaf path: skipping the failure case for Maximum number of distinct nodes in a root-to-leaf path. Interviewers spot it in ten seconds.

Place Maximum number of distinct nodes in a root-to-leaf path next to nearby DSA work — one Maximum number of distinct nodes in a root-to-leaf path step Dev can write from memory is the link.

Viva for Maximum number of distinct nodes in a root-to-leaf path: what it is → one Maximum number of distinct nodes in a root-to-leaf path step Dev can write from memory → the mistake (skipping the failure case for Maximum number of distinct nodes in a root-to-leaf path).
