Problem

You're scanning a buffer of unsorted sensor readings for a peak: any index in `nums` whose value is strictly greater than both of its neighbors, where the space just past either end of the buffer counts as lower than any reading. Return the index of any one such peak. The buffer can be large and lookups must stay logarithmic, so walking every reading is off the table.

Summary

Somewhere the ground stops climbing.
