[ad_1] In your constructor Stack() { top->next = NULL; } top has never been given a value, so top->next is an error. Looks to me that most of your code would be fixed if you replaced top->next with top throughout. There’s another error here void Stack::show() { Node *cur = new Node; cur = top-> … Read more
[ad_1] You can expose any port or set of ports using EXPOSE in Dockerfile. EXPOSE 8080 3000 3001 Generally, the Node application uses default port as 3000. But you can change it with configurations. [ad_2] solved Are there any specifications on what ports are there for back-end application?
[ad_1] It first builds a table of all the solvable boards, represented as numbers, that says how many steps from the solution that board is. Then it solves each test case by looking it up in that table. The time complexity per test case is constant. I doubt that there is anything in the standard … Read more
[ad_1] You can try this: #!/bin/bash while read -r line; do date=”${line:4:8}” echo “$line” >> “${date}.txt” done < filenames.txt 0 [ad_2] solved Creating text files based on list of file names [closed]
[ad_1] that is because you have entered a wrong file mode. You used r which stands for reading while you should use the w for the writing. That code should work. a = open(“movies.txt”,”rw”) a.write(“EndGame”) a.close() 3 [ad_2] solved Writing and reading files [duplicate]

[ad_1] I can safely assume you want to know how to create a dictionary, and how to iterate through it. To create a dictionary: States = {‘Alabama’: ‘.05’, ‘Iowa’: ‘0.04’} To loop through it: for key in States: if key == stateName: #States[key] will return the value associated with the key, ex .05 for Alabama … Read more
[ad_1] No, it is not good. It is considered a good practice to have an adapter as a stand-alone class (not nested one) as it will give you the benefit of code reuse. Also, if you decide that you need a nested class anyway, make it private. I recommend a book from Head First series: … Read more
[ad_1] Your code seams ok but you have to protect your dictionary from external access. I think the root cause of your problem is this. Change your code private readonly Dictionary<string, double> dict = new Dictionary<string, double>(); Also modify the getValue() method like this: public override Object getValue() { return dict.ToDictionary(m => m.Key, m => … Read more
[ad_1] In general, in C++, the order of evaluation of subexpressions is unspecified. Check out the link for more discussion, and some exceptional cases. The C++ standard says: Except where noted, evaluations of operands of individual operators and of subexpressions of individual expressions are unsequenced.[…] The compiler may decide which argument of print (in your … Read more
[ad_1] How to remove duplicate rows while keeping only first row based on duplicate data in B & C columns. Rows to be checked sequentially [ad_2] solved How to remove duplicate rows while keeping only first row based on duplicate data in B & C columns. Rows to be checked sequentially
[ad_1] So this is my solution, there are better ways you can use backtracking to generate sudoku, like just calling fuelleArray(fieldIndex, numberInField). With that, backtracking would be more visible and clear in the code and you won’t have to deal, like I had, with the cases when its on the end of a row. public … Read more
[ad_1] Maybe I am missing something here, but if 350 sq ft requires 1 gallon, then 250 sq ft will require 250/350 gallons. So you are being asked (I suppose) to request the area from the user and calculate the paint required for that area. wall_area=float(input(“How big is your wall in square feet? “)) gallons_paint … Read more
