Jump Game Array

Given an array of non-negative integers, A, you are initially positioned at the 0^th 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.

Input Format:

The first and the only argument of input will be an integer array A.

Output Format:

Return an integer, representing the answer as described in the problem statement.
    => 0 : If you cannot reach the last index.
    => 1 : If you can reach the last index.

Constraints:
1 <= len(A) <= 10⁶

0 <= A[i] <= 30

Examples:

Input 1:
    A = [2,3,1,1,4]

Output 1:
    1

Explanation 1:
    Index 0 -> Index 2 -> Index 3 -> Index 4

Input 2:
    A = [3,2,1,0,4]

Output 2:
    0

Explanation 2:
    There is no possible path to reach the last index.

NOTE: You only need to implement the given function. Do not read input, instead use the arguments to the function. Do not print the output, instead return values as specified. Still have a question? Checkout Sample Codes for more details.
