HackerRank Java No response on stdout

I kept getting "No response on stdout" as I was writing my code, so I copy pasted all of my code into IntelliJ (where it worked more or less), I reset the HackerRank code, and attempted to just print "hello" to stdout. Still no response on stdout. The code below runs fine in IntelliJ as well, so it has to be a HackerRank issue right? Or am I missing something?

to be honest i tried to go to reddit with this, but the sites down and not loading right now. Plus with all the crap that's going on I know a lot of reddit users are moving here to tumblr. So maybe I will start posting more questions here?

I had a hard time waking up today. Yesterdays chores finished at 2am. Incredible. On the good side I have everything ready for the next 2 weeks. I just need a sharp 8 hour focus study routine. Im basically starting from scratch and going step by step since Im very afraid of missing out simple questions. Again if I think about it I have nothing to lose. This is my first serious recruitment process. Whether I get accepted for interview or not I will definitely see the benefits of my work.

While I prepare for the assessment Im trying to not to miss out on classes. Just enough to keep up with the lectures and rest of the time will be fully reserved for solving questions.

Unrelated thought: sometimes I stop and think how come I have no romantic interest/relationships. I feel kind of empty when I think about it. Not like it disrupts my general peace or anything but like how? Maybe this is the "normal". I have people that I admire or I find attractive but the premonition of never finding anyone that I connect with sexually or romantically depresses me. I examine people that are in relationships and compare myself to them to find out what am I missing. I have no motivation to improve whatever I am missing tho, just curiosity.

Staircase - HackerRank Problem Solving

Staircase is a Hackerrank problem from the Algorithms subdomain that requires an understanding of loops and string manipulation. In this post, you will learn how to solve Hackerrank’s Staircase problem and its solution in Python and C++.

Problem Statement and Explanation

Basically, we have to print a staircase of size n. The staircase should be right-aligned, composed of # symbols and spaces, and has a height and width of n.

Input Format

A single integer, n, denoting the size of the staircase.

Output Format

Print a staircase of size n using # symbols and spaces.

Project Euler #2

Welcome back to my series on Project Euler problems. HackerRank Lets get into it.

Links:

Project Euler: https://projecteuler.net/problem=2 HackerRank: https://www.hackerrank.com/contests/projecteuler/challenges/euler002

Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be: 1,2,3,5,8,13,21,34,55,89,… By considering the terms in the Fibonacci sequence whose values do not exceed N, find the sum of the even-valued terms.

So first thing to note is just how odds and evens work. This starts with 1 and 2 so Odd + Even = Odd, then the next term would just be Even + Odd = Odd. It isn't until the 3rd addition that we get Odd + Odd = Even. After that this cycle will repeat.

So really what this is asking for is, starting at index 2, what is the sum of every 3rd term less than N.

F(2) + F(5) + ... + F(3k + 2)

(Where F(N) is the Nth Fibonacci number)

Now, computing Fibonacci numbers notoriously sucks to do, with the naive way of doing it causing you to compute from just F(20) would require computing F(3) like hundreds if not thousands of times over. So the best way to do it is to create either a hash or a cache to store it. I'm going to be utilizing something built into Python, "lru_cache" from the "functools" module. It'll just store the answers for me so I don't have to recompute what F(10) is thousands of times.

Here's my HackerRank code:

import sys from functools import lru_cache @lru_cache def fibonacci(N: int) -> int: if N < 0: return 0 if N <= 1: return 1 return fibonacci(N-1) + fibonacci(N-2) t = int(input().strip()) for a0 in range(t): n = int(input().strip()) x = 2 f = fibonacci(x) total = 0 while f <= n: total += f x += 3 f = fibonacci(x) print(total)

So as you can see, I just start at 2 and keep incrementing by fibonacci number by 3 each time. Then the loop will stop when my fibonacci number exceeds N.

And that's all tests passed! Onto the next one!

Connected Sum Solution for Hackerrank

Problem Statement Given a graph with n nodes and m edges, we need to find the sum of the sizes of connected components in the graph. Each connected component is a subgraph in which every pair of nodes is connected by a path. For example, consider the following graph: 1 - 2 | 3 - 4 | 5 - 6 In this graph, there are 3 connected components: {1, 2}, {3, 4}, and {5, 6}. The sizes of these connected…
