I have an array
foo = %w(1 2 3 4 5 6 7 8 9 10)
How can I split or "chunk" this into smaller arrays?
class Array
def chunk(size)
# return array of arrays
end
end
foo.chunk(3)
# => [[1,2,3],[4,5,6],[7,8,9],[10]]

The following is 2 different definitions of the problem:
How can I process 2 arrays so that I can keep the data of duplicate array[key] values.

REAL*8 X(0:N1,1:N2,0:N3-1),...
...
RETURN
END
Which is called in another subroutine by:
CALL SSUB(W(0,1,0,1),...)
where W is a 'working array'. It appears that a specific…
