By using ghci and simply inputing the code snippets you will see which of the values are accepted: Prelude> data Bin = B Bin | C [ Int] Prelude> a = C [ ] Prelude> b = B ( B C [ 2]) <interactive>:3:9: error: • Couldn’t match expected type ‘[Integer] -> Bin’ with actual … Read more
If you get a NullReferenceException when casting to Animal then it means that Zebra is not a derived class. Although it seems to have a similar structure as the other classes 4 solved Cant see all members in Object (but with `OfType` I can access)
In your switch statement, replace every return; with break; which is the signal to break out of the switch, but the rest of the code will run. When you write return within a void method, when its reached it means you are breaking out of the method itself so no code past it will be … Read more
You can try something like this : input_st = “Field1:’abc’,Field2:’HH:MM:SS’,Field3:’d,b,c'” output_st = {item.split(“:”)[0]:”:”.join(item.split(“:”)[1:]).replace(“‘”, “”) for item in input_st.split(“‘,”)} outputs : {‘Field1’: ‘abc’, ‘Field2’: ‘HH:MM:SS’, ‘Field3’: ‘d,b,c’} Kind of ugly but it does the job. 4 solved Convert string to Ordered Dictionary [closed]
Your second program is malformed. It’s not using std::string::operator[] at all. string * ps = new string(str); ps[0] = ‘n’; Not only does std::string support the [] operator, every pointer to a type also supports the [] operator. It’s how C style arrays work, and it’s what you’re doing in the code above. ps isn’t … Read more
Demo https://jsfiddle.net/mg8zbr41/172/ (I hope this was the desired behaviour) Explanation The whole problem would have been solved if we were allowed to have overflow-x: auto and overflow-y: visible together. But we cannot do that (see this answer). So we use the following workaround. If you want to have want the red div to pop out … Read more
The two main concept that you see in the last line are list comprehension and nested loops. Have a look. for understanding better what is going on, we’re going to split that line in simplier part: TENS for tens in “twenty thirty forty fifty sixty seventy eighty ninety”.split(): print(tens) OUTPUT: twenty thirty forty fifty sixty … Read more
Rules for a.compareTo(b) returns negative value : a is before b returns 0 : a equal to b return positive value : a is after b Because the parameter are first, second and you compare like second.compareTo(first) you’ll get reverse order : (second+first) 344 first+ second 434 comparing : -1 >> 4 is before 34 … Read more

Don’t use [id=all-contents] in the CSS, the # is made for that: #all-contents ! Don’t use spaces in class names ! professional interests → professional_interests, There was … Read more
You could also use media queries. On screens smaller than 600px width the image will be width 100%. On screens larger than 600px width the image width is auto meaning the size of the image. You might want to tweak that 600px for your project. .container { position: relative; margin-top: 10px; } img { width: … Read more
x << 1 is analogous to operations like x * 2. If you don’t store the result anywhere, it is just discarded and the line may just get omitted entirely by an optimizing compiler. If you want to store the result of an operation like that back into x, you have options like: x = … Read more
