All the lambdas use the last factor

Time: 0:00

What it should do

make_multipliers([2, 3, 4]) should build one multiplier per factor, so the FIRST one doubles: apply_first([2, 3, 4], 10) returns 20.

What goes wrong

apply_first([2, 3, 4], 10) returns 40 — the first multiplier is using 4, the last factor, instead of 2.

Hints

This is a scope and closure bugs bug

Every callback reports the last value, a counter never increments, UnboundLocalError on a variable you can see.
