QUESTION
I'm trying to pass data from a tableView when the cell is tap to a detailTableView. I'm not getting any errors when the detail tableView is loaded. The segue is being performed, however, the tableView remains blank. My goal to add the color to the textLabel in the cell and add the zord in the detailTextLabel within the same cell. Can someone tell me what I'm doing wrong

QUESTION
I am currently on the path of learning C++ and this is an example program I wrote for the course I'm taking. I know that there are things in here that probably makes your skin crawl if you're experienced in C/C++, heck the program isn't even finished, but I mainly need to know why I keep receiving this error after I enter my name: Exception thrown at 0x79FE395E (vcruntime140d.dll) in Learn.exe: 0xC0000005: Access violation reading location 0xCCCCCCCC.
I know there is something wrong with the constructors and initializations of the member variables of the classes but I cannot pinpoint the problem, even with the debugger. I am running this in Visual Studio and it does initially run, but I realized it does not compile with GCC. Feel free to leave some code suggestions, but my main goal is to figure out the program-breaking issue.

I am running the following program. In this program, I have the Cow class, the Dragon class derived from the Cow class, and the IceDragon class derived from the Dragon class. The Cow class, the Dragon class, and the Ice dragon class are implemented in a class called HeiferGenerator. I am running the main function in a class called CowSay, where I am implementing the HeiferGenerator class along with the Cow class, Dragon class, and IceDragon class. However, look below at the HeifeferGenerator class. I am getting the warning "Raw use of parameterized class 'Class' " on the line:
...ANSWER
Answered 2021-Mar-31 at 16:38TL;DR: Do you HAVE to use arrays? If not, use lists
Replace this:
Constructor constructor = dragonTypes[index].getConstructor(String.class, String.class);
With this:
Constructor constructor = dragonTypes.get(index).getConstructor(String.class, String.class);
And this:
private static final Class[] dragonTypes = {Dragon.class, Dragon.class};
With this:
private static final List> dragonTypes = Arrays.asList(Dragon.class, Dragon.class);

QUESTION
I am stuck to a problem from the famous dragon Book of Compiler Design.How to find all the viable prefixes of the following grammar:
...ANSWER
Answered 2021-Jun-06 at 22:140n1n
is not a regular language; regexen don't have variables like n
and they cannot enforce an equal number of repetitions of two distinct subsequences. Nonetheless, for any context-free grammar, the set of viable prefixes is a regular language. (A proof of this fact, in some form, appears at the beginning of Part II of Donald Knuth's seminal 1965 paper, On the Translation of Languages from Left to Right, which demonstrated both a test for the LR(k) property and an algorithm for parsing LR(k) grammars in linear time.)
OK, to the actual question. A viable prefix for a grammar is (by definition) the prefix of a sentential form which can appear on the stack during a parse using that grammar. It's called "viable" (which means "still alive" or "could continue growing") precisely because it must be the prefix of some right sentential form whose suffix contains no non-terminal symbol. In other words, there exists a sequence of terminals which can be appended to the viable prefix in order to produce a right-sentential form; the viable prefix can grow.
Knuth shows how to create a DFA which produces all viable prefixes, but it's easier to see this DFA if we already have the LR(k) parser produced by an LR(k) algorithm. That parser is a finite-state machine whose alphabet is the set of terminal and non-terminal symbols of a grammar. To get the viable-prefix grammar, we use exactly the same state machine, but we remove the stack (so that it becomes just a state machine) and the reduce actions, leaving only the shift and goto actions as transitions. All states in the viable-prefix machine are accepting states, since any prefix of a viable prefix is itself a viable prefix.
A key feature of this new automaton is that it cannot extend a prefix with a reduce action (since we removed all the reduce actions). A prefix with a reduce action is a prefix which ends in a handle -- recall that a handle is the right-hand side of some production -- so another definition of a viable prefix is that it is a right-sentential form (that is, a possible step in a derivation) which does not extend beyond the right-most handle.
The grammar you are working with has only two productions, so there are only two handles, 01
and 0S1
. Note that 10
and 1S
cannot be subsequences of any right-sentential form, nor can a right-sentential form contain more than one S
. Any right-sentential form must either be a sentence 0n1n
or a sentential form 0nS1n
where n>0
. But every handle ends at the first 1
of a sentential form, and so a viable prefix must end at or before the first 1
. This produces precisely the four possibilities you list, which we can condense to the regular expression 0*0(S1?)?
.
Chopping off the suffix removed the second n
from the formula, so there is no longer a requirement of concordance and the language is regular.
Questions like this and their answers are begging to be rendered using MathJax. StackOverflow, unfortunately, does not provide this extension, which is apparently considered unnecessary for programming. However, there is a site in the StackExchange constellation dedicated to computing science questions, http://cs.stackexchange.com, and another one dedicated to mathematical questions, http://math.stackexchange.com. Formal language theory is part of both computing science and mathematics. Both of those sites permit MathJax, and questions on those sites will not be closed because they are not programming questions. I suggest you take this information into account for questions like this one.

Line breaks are getting added to the elements in the list after split. I have seen it on windows now happen as well.

I have a game built in JavaScript where you drag coins from underneath a dragon into a vault to score points.
Game for reference: https://codeeverydamnday.com/projects/dragondrop/dragondrop.html
You only get the points if you drop the coin within the bounds of the vault. The vault bounds are within these absolute positions:
Left edge of vault: 645px from left side of screen
Right edge of vault: 915px from left side of screen
Top edge of vault: 290px from top edge of screen
Bottom edge of vault: 540px from top edge of screen
On the function that runs when you drop the coin, I have an "if" statement that adds up your score only if the coin you drop has new x-y coordinates that fall within the vault bounds (only relevant code shown, can provide more if needed):
...ANSWER
Answered 2021-May-31 at 00:34I figured out the answer to my problem. I was trying to compare two string values instead of two number values.
In the code below (shortened to relevant code from description above), the coin.style.left
value might end up being something like "760px"
, for example.

Install dragon
You can use dragon like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the dragon component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
