In this problem Clara plays a simplified version of the Pacman game. She is positioned on top of the first of a long trail of leaves $($as shown in Figure $1).$ She must pick up all leaves and stop when all the leaves are collected $($as shown in Figure $2]$ and the leaf trail is over. The leaf trail always ends with a tree.

The most important characteristics of your solution are:

There must be no leaves after program stops rurning

Leaves must be removed in correct order starting with the leaf under Clara and ending with the leaf next to a tree
