+/**
+ * JumpingClouds
+ * There is a new mobile game that starts with consecutively numbered clouds.
+ * Some of the clouds are thunderheads and others are cumulus. The player can
+ * jump on any cumulus cloud having a number that is equal to the number of the
+ * current cloud plus or
+ * 
+ * . The player must avoid the thunderheads. Determine the minimum number of
+ * jumps it will take to jump from the starting postion to the last cloud. It is
+ * always possible to win the game.
+ * 
+ * For each game, you will get an array of clouds numbered
+ * if they are safe or
+ * 
+ * if they must be avoided.
+ * 
+ * Example
+ * Index the array from . The number on each cloud is its index in the list so
+ * the player must avoid the clouds at indices and . They could follow these two
+ * paths: or . The first path takes jumps while the second takes . Return
+ * 
+ * .
+ * 
+ * Function Description
+ * 
+ * Complete the jumpingOnClouds function in the editor below.
+ * 
+ * jumpingOnClouds has the following parameter(s):
+ * 
+ * int c[n]: an array of binary integers
+ * 
+ * Returns
