Micro-Drill #2 — Find min and max

Pointer Manipulation Target: 10s

Single-pass min/max tracking is the basis for best-time-to-buy-stock and range queries.

mn, mx = min(a), max(a)

# Manual loop:
mn = mx = a[0]
for x in a[1:]:
    if x &lt; mn: mn = x
    if x &gt; mx: mx = x

Type it from memory. Go.
