단방향 연결 리스트(singly linked list)가 주어지면 총 합이 0으로 되는 연결된 노드들을 뺀 뒤 남은 노드의 값을 프린트 하시오.
Given a linked list, remove consecutive nodes that sum to zero. Print the values of leftover nodes.

output: 3 -> 1 -> 2 -> 3
input: 1 -> 2 -> 3 -> 4 -> (-10) -> 5

왜 Docker를 사용해야하는가?

Why Should I Care (For Developers)

"나에게 Docker의 매력은 간단히 격리된 환경을 만들 수 있다는 것과, 그러한 환경을 재사용할 수 있다는 점이다."런타임 환경을 한 번 만들어 패키지로 만들면, 이 패키지를 다른 어떤 머신에서도 다시 사용할 수 있다. 또한 여기서 실행되는 모든 것은 마치 가상머신과 같이 호스트로부터 격리되어있다. 무엇보다도 이런 모든 일들이 빠르고 간단히 가능하다.

HBase Stargate REST API Scanner Filter Examples

Stargate Scanner Filter Examples

Introduction

So yeah... no documentation for the HBase REST API in regards to what should a filter look like...

So I installed Eclipse, got the library, and took some time to find some of the (seemingly) most useful filters you could use. I'm very green at anything regarding HBase, and I hope this will help anyone trying to get started with it.

What I discovered is that basically, attributes of the filter object follow the same naming than in the documentation. For this reason, I have made the link clickable and direct them to the HBase Class documentation attached to it; check for the instantiation argument names, and you will have your attribute list (more or less).
