Method Detail

getLongestConsecutiveSubList

public static List<Integer> getLongestConsecutiveSubList(int offsetIndex,
                                                         List<Integer> intList)

extract a sublist of the first consecutive range of integers found in the given list, e.g., without gaps so for 0,2,4,6,7,8,9,10,12 with offset 5, we find ,8,9,10. In case offset is 0, we only get 0 back

Parameters:

offsetIndex - (inclusive)

intList - to extract longest sublist from

Returns:

sublist, empty if out of range

rangeOf

public static List<Integer> rangeOf(int start,
                                    int end)

Create a range between start and end

Parameters:

start - inclusive

end - exclusive

Returns:

integer list in ascending order
