It seems inconceivable that the purpose of your assignment determining the frequency of word-pairs in a file would be to have you wrap a piped-string of shell utilities in a system call. What does that possibly teach you about C? That a system function exists that allows shell access? Well, it does, and you can, … Read more
The first issue is that the temp, temp2, and temp3 are int, but you are assigning double values to them, and then re-assigning these values back to double variables. You should make these double. You might want to consider using qsort() to sort these objects. #include <stdlib.h> // for qsort int compare_products(const void *p1, const … Read more

The definition of valid_list should be out of the for loop, otherwise it will be overwritten. Besides, use a flag_valid to indicate whether the invalid elements exist. Try this code: from itertools import permutations def code(): valid_list = [] for line,lists in enumerate(permutations(range(4))): flag_valid = True for index,elements in enumerate(lists): if index != len(lists) – … Read more

First create a Calendar for the UTC timezone. Second get the startOfDay using the UTC calendar. Third add one day to that date. Then you can useDatemethodtimeIntervalSince(_ Date)` to calculate the amount of seconds between those two dates: extension Calendar { static let iso8601UTC: Calendar = { var calendar = Calendar(identifier: .iso8601) calendar.timeZone = TimeZone(identifier: … Read more

First of all, and that’s supposed to solve the problem. If you use an ArrayList you should check its documentation. When you supposed to go through a simple array you use “nameOfArray.length”, right? Well, the ArrayList has the method “.size()” which bascialy has the same use. So your loop would be better this way : … Read more
Here what you could do: Enumerate the link attribute. Check for each value if it’s the one you want (the one that starts with “applewebdata://”). Modify either the rest of the string and/or the link (your question is unclear on that part, I made both). attributedString needs to be mutable (NSMutableAttributedString). attributedString.enumerateAttribute(.link, in: NSRange(location: 0, … Read more

They’re known as infix operators, and they’re inbuilt, and act like Function prototypes. It’s interesting to note that regular JavaScript doesn’t support things like exponentiation through infix operators, and you’re forced to resort to an extension of Math: console.log(Math.pow(7, 2)); Although ES6 fixes this: console.log(7 ** 2); Although you can’t create your own infix operators, … Read more
