/**

* Given an array of non-negative integers, you are initially positioned at the

* first index of the array.

*

* Each element in the array represents your maximum jump length at that

* position.

*

* Determine if you are able to reach the last index.

*

* For example: A = [2,3,1,1,4], return true.

*

* A = [3,2,1,0,4], return false.
