What statement is NOT true?

Choose $1$ answer.

Functional iterators such as map $()$ are

considerably faster than the equivalent for $()$

loop.

Functional iterators such as map $()$ result in fewer

lines of code as compared to a for $()$ loop.

Walk $()$ is just like map $()$ but doesn't return a

value.

A for $()$ loop iterates over a sequence vector,

which doesn't have to be a contiguous range of

values.

Vectorized functions perform considerably faster

than for $()$ loops.
