Python: nested lambdas — `s_push: parser stack overflow Memory Error`

寵の児 提交于 2019-11-29 07:33:04
I recently stumbled across this article which describes how to code FizzBuzz using only Procs in Ruby, and since I was bored, thought it would be neat to try and implement the same thing in Python using lambdas. I got to the section where you create numbers using nested functions, and wrote the following Python script: #!/usr/bin/env python zero = lambda p : (lambda x: x) one = lambda p : (lambda x: p(x)) two = lambda p : (lambda x: p(p(x))) three = lambda p : (lambda x: p(p(p(x)))) five = lambda p: (lambda x: p(p(p(p(p(x)))))) fifteen = lambda p : (lambda x: p(p(p(p(p( \ p(p(p(p(p( \ p(p(p(p

An unhandled exception of type 'System.StackOverflowException' occurred

Why this? This is my code : public class KPage { public KPage() { this.Titolo = "example"; } public string Titolo { get { return Titolo; } set { Titolo = value; } } } I set data by the constructor. So, I'd like to do somethings like KPage page = new KPage(); Response.Write(page.Titolo); but I get that error on : set { Titolo = value; } You have an infinite loop here: public string Titolo { get { return Titolo; } set { Titolo = value; } } The moment you refer to Titolo in your code, the getter or setter call the getter which calls the getter which calls the getter which calls the getter which

Is iteration faster than recursion, or just less prone to stack overflows?

I know you can rewrite a recursive function using a simple loop by using an array as a first-in-first-out queue of 'work remaining to be done'. I have heard this makes it less likely to have a stack overflow. But if stack overflows aren't an issue (because you're not recursing very deeply), is there any reason to prefer iterative over recursive? Is it any faster? I'm mostly interested in JavaScript on V8. In Javascript, which doesn't (isn't required to, and perhaps can't? see the comments) do tail-recursion optimisation, recursion is both slower than iteration (because, in almost every

What is and how to fix System.TypeInitializationException error?

private static void Main(string[] args) { string str = null; Logger.InitUserLogWithRotation(); // <--- error occur ... } When I build project, it has no error. But When I execute it, it always aborted. I tried to debug project , but System.TypeInitializationException error occurred at first line. I've already tried to googling , yet found no solution. It seems like any variable initialize code is wrong , but can't find it. Please help me. I'm new to C#. Thanks. ※ Here is Logger Class Code public class Logger { private static int HDLOG_PRIORITY_DEBUG = 4; private static int HDLOG_PRIORITY_ERROR

How to solve 'protection stack overflow' issue in R Studio

I'm trying to build a model with the glmnet package, but I'm getting the following error when I run the following line: #library('glmnet') x = model.matrix(response ~ ., data = acgh_frame[,c(3:ncol(acgh_frame))]) Error: protect(): protection stack overflow I know this is due to my large number of variables (26k+) in the dataframe. When I use fewer variables the error doesn't show. I know how to solve this in command line R, but I require to stay in R studio, so I want to fix it from R Studio. So, how do I do this? @Ansjovis86 You can specify the ppsize as a command line argument to Rstudio

C# - Entity Framework - An unhandled exception of type 'System.StackOverflowException' occurred in mscorlib.dll

An unhandled exception of type 'System.StackOverflowException' occurred in mscorlib.dll Make sure you do not have an infinite loop or infinite recursion. The below code is called on a success of this method: internal static List<RivWorks.Model.Negotiation.ProductsSold> GetProductsSoldByCompany(Guid CompanyID) { var ret = from a in _dbRiv.ProductsSold where a.Company.CompanyId == CompanyID select a; return ret.ToList(); } On the return it calls into the Entity Model and tries to populate all foreign keyed objects (child objects). The schema is [1 Company has 0 to many ProductsSold]. For some

java.lang.StackOverflowError due to recursion

回眸只為那壹抹淺笑 提交于 2019-11-28 21:39:16
My problem is that I usually get a java.lang.StackOverflowError when I use recursion. My question is - why does recursion cause stackoverflow so much more than loops do, and is there any good way of using recursion to avoid stack overflow? This is an attempt to solve problem 107 , it works well for their example but runs out of stack space for the problem it self. //-1 16 12 21 -1 -1 -1 16 -1 -1 17 20 -1 -1 12 -1 -1 28 -1 31 -1 21 17 28 -1 18 19 23 -1 20 -1 18 -1 -1 11 -1 -1 31 19 -1 -1 27 -1 -1 -1 23 11 27 -1 public class tries { public static int n=7,min=Integer.MAX_VALUE; public static

Help catching StackOverflowException with WinDbg and ADPlus

有些话、适合烂在心里 提交于 2019-11-28 20:37:58
Short Version I want an ADPlus script that will do a full memory dump on the first-chance StackOverflowException, before anything is cleaned up, and ignore all other exception types. Log Version After a release of new ASP.NET code, we started getting intermittent StackOverflowExceptions. We've looked for infinite recursions and all the usual suspects in the revisions added since the last known good install, and can't find anything. The website will run for up to an hour, and then crash down. We've used WinDbg and SOS and attempted to get crash logs using ADPlus, using this command: adplus

Understanding the Java stack

问题 There is this code: public class Main { public static void main(final String[] args) throws Exception { System.out.print("1"); doAnything(); System.out.println("2"); } private static void doAnything() { try { doAnything(); } catch (final Error e) { System.out.print("y"); } } } And there is the output: 1yyyyyyyy2 Why does it print "y" eight times and no more. How can Java call println() when StackOverflowError encountered? 回答1: Here you are catching Error and not Exception in which case your

Confusing output from infinite recursion within try-catch
