stack

问题 Enemy classes involved: public abstract Enemy : MonoBehaviour {} public class A : Enemy {} public class B : Enemy {} I have a dictionary. I want make the dictionary contain a stack for every type of Enemy. public class Test : MonoBehaviour { // prefabs public GameObject a, b; public Dictionary<Enemy, Stack> eDictionary; void Start() { eDictionary = new Dictionary<Enemy, Stack>(); Fill(a, 10); Fill(b, 10); } } How I make the stack and keys. public void Fill(Enemy e, int howMany) { Stack s =

问题 I'm currently learning about operating systems and I learned that the stack is located between the kernel and the heap. What confuses me is that in most implementations, since the stack tends to grow downwards while the heap grows to higher memory addresses what is stopping the stack from growing into the heap? If it were possible what would happen if it did grow into the heap? 回答1: This is not necessarily correct: I'm currently learning about operating systems and I learned that the stack is

问题 How can I clear the back stack in windows apps (not windows phone)? I am using MvvmCross v3. Where is the most correct place to put it? I have read this post http://edsnider.net/2014/04/07/clearing-windows-phone-nav-back-stack-in-mvvmcross/ where he is using CustomWP8ViewPresenter public override void ChangePresentation(MvxPresentationHint hint) { if (hint is ClearNavBackStackHint) { while (RootFrame.BackStack.Any()) { RootFrame.RemoveBackEntry(); } } base.ChangePresentation(hint); } My

问题 I'm working on an assignment for class. We were provided with these three classes. (Linked here, the editor was flipping out when I tried to do them on separate lines). We're supposed to take in a string and then use these classes to test if it's a palindrome. We can't modify said classes. And here's my int main : #include <iostream> #include <cstring> #include <cctype> #include "stack.h" using namespace std; int main () { char testString[100]; Stack<char> charStack; cout << "Please enter a

问题 I have a wide dataframe that I want to stack and pivot and can't quite figure out how to do it. Here is what I am starting with testdf = pd.DataFrame({"Topic":["A","B","B","C","A"], "Org":[1,1,2,3,5,], "DE1":["a","c","d","e","f"], "DE2":["b","c","a","d","h"], "DE3":["a","c","b","e","f"] }) testdf Out[40]: DE1 DE2 DE3 Org Topic 0 a b a 1 A 1 c c c 1 B 2 d a b 2 B 3 e d e 3 C 4 f h f 5 A What I would like to do is pivot the table so that the column values for Org are the Column names and the

问题 (This question is related to Filtering out junk from valgrind output). I'm trying to debug memory leaks in a large project that is mostly out of my hands --- it's a fork of a codebase that's on the order of millions of lines of code, although most of it probably isn't relevant to the small section that I'm working on. Since it would be very tough to look through it by hand, I'm trying to use valgrind to track down the leaks. The problem is that the stack traces look like this: ==83597== 920

问题 Well first I understand (or a I think that I understand) the problems of misaligned stack. But I know (like a definition) that pushing a 16bit value to 32bit wide stack could cause a stack misaligned. But the thing I dont understand, is how this could happend...since PUSH and POP check the D flag at the segment descriptor (so is 1 increments/decrements 32bits and is 0 16bits). Suppose that D flag=1, should PUSH AX do a 32bits decrement? so its like I "miss" 16bits in the stack? I am not sure

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 8 years ago . I'm using a Stack in Java. The problem is that I only can push 10 items into the stack, and I need to push 20 items. How do I increment the capacity of the stack? 回答1: Java's Stack class inherits from Vector and

问题 For example if the parenthesis/brackets is matching in the following: ({}) (()){}() () and so on but if the parenthesis/brackets is not matching it should return false, eg: {} ({}( ){}) (() and so on. Can you please check this code? Thanks in advance. public static boolean isParenthesisMatch(String str) { Stack<Character> stack = new Stack<Character>(); char c; for(int i=0; i < str.length(); i++) { c = str.charAt(i); if(c == '{') return false; if(c == '(') stack.push(c); if(c == '{') { stack

问题 This question already has answers here : Fields of class, are they stored in the stack or heap? (3 answers) Closed 3 years ago . The earlier post dealt with the value and reference types and their memory allocation. Here I'm trying to understand the memory allocation of static members. I have a simple class which has got both static and non-static integers like one shown below. class Sample { public int nonStaticInt = 0; public static int staticInt = 0; } My question here is, where do static
