Jump is a simple one-player game:
You are initially at the first cell of an array of cells containing non-negative integers; at each step you can jump ahead in the array as far as the integer at the current cell, or any smaller number of cells. You win if there is a path that allows you to jump from one cell to another, eventually jumping past the end of the array, otherwise you lose. For instance, if the array contains the integers [2, 0, 3, 5, 0, 0, 3, 0, 0, 3, 1, 0], you can win by jumping from 2, to 3, to 5, to 3, to 3, then past the end of the array.
Your task is to write a program that determines if a given game is winnable. When you are finished, you are welcome to read or run a suggested solution, or to post your own solution or discuss the exercise in the comments below.
