You are given an integer array `nums`. You are initially positioned at the array's **first index**, and each element in the array represents your maximum jump length at that position.
Return `true` if you can reach the last index, or `false` otherwise.
Example 1
Input:nums = [2,3,1,1,4]
Output:true
Explanation:Jump 1 step from index 0 to 1, then 3 steps to the last index.
Example 2
Input:nums = [3,2,1,0,4]
Output:false
Explanation:You will always arrive at index 3 no matter what. Its maximum jump length is 0, which makes it impossible to reach the last index.
