This is a variant of this leetcode question, but instead of returning the count, we want to return the actual contiguous sub arrays. For example, if num = [1,2,4,7] k=7 the returned value should be [[1,2,4],[7]] . I used a hashmap to store the cumulative sum up to all the indices possible along with the number of times the same

Find the point where maximum intervals overlap for certain interval length
I’m trying to maximize attendance to a event given a list of busy times for each person. The event can be scheduled anytime between a certain date and hours (Ex. March 1st to March 8th from 9-5) and that attendance is maximized. So far I’ve tried using a sliding window approach, and a counting approach described here (https://www.geeksforgeeks.org/find-the-point-where-maximum-intervals-overlap/) however I
CodeSignal reverseParentheses Failing one case
Write a function that reverses characters in (possibly nested) parentheses in the input string. Input strings will always be well-formed with matching ()s. For inputString = “(bar)”, the output should be reverseInParentheses(inputString) = “rab”; For inputString = “foo(bar)baz”, the output should be reverseInParentheses(inputString) = “foorabbaz”; For inputString = “foo(bar(baz))blim”, the output should be reverseInParentheses(inputString) = “foobazrabblim”. [input] string inputString A

Recalculation next position (x and y) based on rotate to N degree
I need to calculate the next position of the shape (X and Y) but don’t have any idea how. I tried different solutions but all-time something went wrong. Maybe someone can help me, I need a tip how it calculates, for best understand I will add screenshots. Description: I have the image of the map in the background. I drew
JavaScript: Detect a Loop in a Hierarchical Graph
Note that I’ve already gone through How to detect a loop in a hierarchy of javascript elements In our case, we’re not dealing with a linked-list, but a hierarchical graph where each node may have multiple children linked to it. For example, In this graph, we should detect the loop a -> b -> c -> a. Answer If you
how to filter an nested objects inside an array in javascript
I have the following nested objects in an array and i want to filter the result to return the id of a specific item. The solution i tried is returning null because of the nested objects structure i presume P.S: The structure of the data above is from the backend that iam working with.

Why is this recursion example giving me an infinite loop?
This is driving me insane. Here is the code : Why is this giving me an infinite loop when it’s supposed to print ‘laugh’ 10 times? Answer Like other answers said, each laugh() created a new local counter. The most appropriate recursive method here is to pass the counter as an argument: This is a pure function approach, reducing the
Given a string s, find the length of the longest substring without repeating characters
Example Input: s = “abcabcbb” Output: 3 Explanation: The answer is “abc”, with the length of 3. I tried writing this but if condition is never being exceuted. I am not able to figure out the reason. Answer This is the same algorithm as described by danhuong, simply written with a recursive call and no mutable variables.
