            How does Linq know the name of an element?
            Asked 2022-Feb-15 at 22:15

            I’ve solved a C# beginner Kata on Codewars, asking to return a string[] with only 4-character names. I used a list that is filled in an if statement and then converted back to a string and returned.

            My question is regarding the best practice solution below, which is presented later.

            I understand that the same string[] that comes as an argument is refilled with elements and returned. But how does the program know that each element of the array is called “name”, as it’s never mentioned before?

            Does linq know that a variable with a singular name is an element of a plural name group, here “names”?

            Thanks for helping out!

            I understand that the same string[] that comes as an argument is refilled with elements and returned.

            No, absolutely not. A new sequence of strings is returned based on the input array. The input array is not modified or changed in any way.

            But how does the program know that each element of the array is called “name”, as it’s never mentioned before?

            name is a parameter to an anonymous function. The name parameter is a string based on context. This could be x or ASDASDASD or whatever you want, but here we use name since we have, on each call, one "name" from names.

            Thus,

            • names is an array of strings passed into the function
            • the .Where returns a new IEnumerable from the current array based on a predicate function (e.g. returns true for a match, false to omit)
            • The predicate name => name.Length == 4 takes a string and returns true if the string is length 4
            • The return from the function is the strings from names that are exactly 4 characters in length

            After doing some testing, I noticed that the a string is not the same in both cases (With the if __name__ == "__main__" and without it). The problem is that when you use if __name__ == "__main__" you indent the a string once to put it inside the if statement. It might seem like you indented the code block, but you actually put spaces inside the string itself.

            With the if __name__ == "__main__":

            Present Sequence as a sum of 2 squares
            Asked 2022-Jan-14 at 19:03

            I was solving a CodeWars task and faced a problem.

            In it you are given the array of numbers, which length is a multiple of 4, you need to visualise it as a (x1^2 + x2^2) * (x3^2 + x4^2) .... * (xn^2 + xn+1^2).

            Calculate the result of this and find 2 numbers, which squares in sum, gives the result of initial sequance. For example, you are given an array of ( 2, 1, 3, 4): (2^2 + 1^2) * (3^2 + 4^2) = 125;

            2 numbers, which squares in sum will give 125, is 2 and 11 because 4 + 121 = 125;

            I wrote the code and it works with most of examples, but when i use big arrays such as (3, 9, 8, 4, 6, 8, 7, 8, 4, 8, 5, 6, 6, 4, 4, 5) in result i receive (0,0);

            You solution is too slow effectively, as it is related to the range of data, which may be huge.

            If n is the number of intervals, here is a O(n logn) solution.

            1. Sort the intervals according to the start of them, and if equal to the end of them

            2. Perform an iterative linear examination of the intervals as follows:

              • sum = 0
              • current_start = interval[0].first
              • current_end = interval[0].second
              • Do i = 1 to n-1
                • if (interval[i].first > current_end) then
                  • sum += current_end - current_start
                  • current_start = interval[i].first
                  • current_end = interval[i].second
                • else
                  • current_end = max (current_end, interval[i].second)
              • sum += current_end - current_start

            At least this problem:

            Off by 1

            OP's code allocations do not account for space needed by the null character. strlen() reports a string's length, not including the null character. An allocation needs to account for the size of a string, which does include null character.
