/**********************************************************************************
*
* 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.
*
*
**********************************************************************************/
