# output:
# ["three", "lol", "zarglezargle", "jambo"]
# 'one' and 'two' are skipped because they are not > 3 characters in length
# 'three' triggers the left side of the flip-flop condition
# 'lol' is selected because the left side has triggered, but not the right side
# 'zarglezargle' triggers the right side condition, and 'turns off' the flip-flop
# Because we used '..' here instead of '...' in the flip-flop, the condition returns true
