Fuzzy logic is logic where state membership is, essentially, a float with range 0..1 instead of an int 0 or 1. The mileage you get out of it is that things like, for example, the changes you make in a control system are somewhat naturally more fine-tuned than what you’d get with naive binary logic. … Read more
The original design motivation for allowing order-comparisons of arbitrary objects was to allow sorting of heterogeneous lists — usefully, that would put all strings next to each other in alphabetical order, and all numbers next to each other in numerical order, although which of the two blocks came first was not guaranteed by the language. … Read more
(This is a generalization of your idea for two arrays.) If you start by looking at the five medians of the five arrays, obviously the overall median must be between the smallest and the largest of the five medians. Proof goes something like this: If a is the min of the medians, and b is … Read more
Make sure you know your basic data structures and algorithms. You’re more likely to be asked about that stuff than something higher up the food chain. Those are usually saved for the in-person interview. Put another way: be solid with the fundamentals and solid with your C++ syntax. Also, knowledge of common libraries like STL … Read more
Add multiple comparable strings into an array and then compare. Reverse the order of comparison. expect([“New”, “In Progress”]).toContain(Status);
If you are extending your form from a ModelForm, use the instance keyword argument. Here we pass either an existing instance or a new one, depending on whether we’re editing or adding an existing article. In both cases the author field is set on the instance, so commit=False is not required. Note also that I’m … Read more
Sorry, this may be too late. But I had similar requirement and found a better way to do this: {{#users.length}} <ul> {{#users}} <li>{{.}}</li> {{/users}} </ul> {{/users.length}} {{^users.length}} <p>No Users</p> {{/users.length}} Working sample here: http://jsfiddle.net/eSvdb/
There’s an answer here using min/max and no branches (https://stackoverflow.com/a/14676309/2233603). Actually 4 min/max operations are enough to find the median, there’s no need for xor’s: median = max(min(a,b), min(max(a,b),c)); Though, it won’t give you the median value’s index… Breakdown of all cases: a b c 1 2 3 max(min(1,2), min(max(1,2),3)) = max(1, min(2,3)) = max(1, … Read more
If my driveway is empty, I cannot assert that all cars parked there are red. Consider the following statements. S1: My driveway is empty. S2: All the cars parked in my driveway are red. I claim that S1 implies S2. That is, the statement S1 => S2 is true. I will do this by showing … Read more
Yes. It’s supported as of .NET 4.7 and C# 8. The syntax is nearly what you mentioned, but with some parenthesis (see tuple patterns). switch ((intVal1, strVal2, boolVal3)) { case (1, “hello”, false): break; case (2, “world”, false): break; case (2, “hello”, false): break; } If you want to switch and return a value there’s … Read more
