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.

Constraints:

Time Complexity

O(n)

Space Complexity

O(1)

Hint

Understand Before Coding

Step 1 / 18

Speed: 1.0x

Array State & Goal Post

Algorithm Commentary

Step 1 of 18

Current Action

Check if we can reach the last index. We use a greedy strategy working backward from target index 4.

Variables

nums[2, 3, 1, 1, 4]
