18. Climbing Stairs
Count distinct ways to climb n steps taking 1 or 2 at a time — Tesla uses this DP foundation to reason about battery-mode transition sequences where each energy state can shift by one or two regeneration levels.

26. Binary Search
Locate a target in a sorted array in O(log n) — Tesla applies binary search in firmware to locate the calibration threshold entry for a given temperature bin within a sorted lookup table used by the battery management system.
