Data engineers are IT professionals who are needed in almost every industry. Data engineers monitor data trends to determine best next steps for companies. A critical part of a data engineer job is to process raw data into usable data by creating data pipelines and building data systems.
// Given a singly linked list without values defined by: class Node { Node next } // Write a function that removes all elements from the list whose _index_ is a fibonacci number // o -> o -> o -> o -> o -> o -> o -> o -> o -> o -> o -> o // 0 1 2 3 4 5 6 7 8 9 10 11 // x x x x x // becomes // o ----------------> o ------> o -> o ------> o -> o -> o // 0 4 6 7 9 10 11
