Hint: In C, C++, and Java, probably the best solution is to create a recursive helper function printPathsRecur(node, int path[], int pathLen), where the path array communicates the sequence of nodes that led up to the current call. Alternately, the problem may be solved bottom-up, with each node returning its list of paths.

Simple Array Rotation Game Erica has two arrays of integers. The first consists of distinct, positive integers and is her work array. The second holds a list of integers defining operations on the work array. For each element of the second list, apply that number of left circular rotations on the original work array.
If there is one thing I got out of public school, it was how to use the book's index and find the answers to questions, or the solutions to problems. This is different from, say, engineering the utility of deque and rotate on your own. But, HackerRank didn't ask me to engineer it from scratch. They just ask you to solve the problem.
