Indexing query

Hi.

To clarify slicing in Ruby, does writing the first number just apply for the index position?

For example, if i wrote '(5, 2)', does this mean to start at position/index 5 and from position 5 onwards, remove 2 items? Further, if one put (8, 1) or (0, 3), it always means start at the position of the first number in the parenthesis?

Thanks,

slice(start, length) will return (not remove) the array at index(start) and for (length) many positions.

slice! will remove them from the array.

see below for a nice explanation: http://ruby-doc.org/core-2.2.2/Array.html#method-i-slice
