static boolean	isGoodReport(List<Integer> nums)	Overload of isGoodReport that doesn't exclude any entry from the report (-1 index is never used)
static boolean	isGoodReport(List<Integer> nums, int excludeIndex)	Tells you whether the report is good.
Integer	partOne(PuzzleInput inputUsed)	Check is each line is a good report, and add up the count
Integer	partTwo(PuzzleInput inputUsed)	Check is each line is a good report, including ones that may be made into good reports by removing a single entry, then adds up the count
static boolean	testAllIterationsOfReport(List<Integer> nums)	I hate that this works and isn't even prohibitively slow.

Method Details

testAllIterationsOfReport

public static boolean testAllIterationsOfReport(List<Integer> nums)

I hate that this works and isn't even prohibitively slow. We're just taking the naive approach of testing every possible variant of the given report. There's probably a faster way to do it involving keeping track of how many errors there have been, but this works so whatever.

Parameters:

nums - the report

Returns:

whether any variation of the report can be good

isGoodReport

public static boolean isGoodReport(List<Integer> nums)

Overload of isGoodReport that doesn't exclude any entry from the report (-1 index is never used)

Parameters:

nums - the report

Returns:

whether the report is good

isGoodReport

public static boolean isGoodReport(List<Integer> nums,
 int excludeIndex)

Tells you whether the report is good. The logic will skip the given index, allowing us to test variations of the given report that have any particular element removed w/o any copy operations

Parameters:

nums - the report

excludeIndex - an index of an entry to skip in the report. negative numbers will have no effect

Returns:

whether the report is good

partOne

public Integer partOne(PuzzleInput inputUsed)

Check is each line is a good report, and add up the count

Specified by:

partOne in class BaseSolution

Parameters:

inputUsed - the PuzzleInput to be used for the solution

Returns:

string containing the number of good reports

partTwo

public Integer partTwo(PuzzleInput inputUsed)

Check is each line is a good report, including ones that may be made into good reports by removing a single entry, then adds up the count

Specified by:

partTwo in class BaseSolution

Parameters:

inputUsed - the PuzzleInput to be used for the solution

Returns:

string containing the number of good reports
