Problem Statement of Reach End of Array With Max Score

You are given an integer array nums of length n.
Your goal is to start at index 0 and reach index n – 1. You can only jump to indices greater than your current index.
The score for a jump from index i to index j is calculated as (j – i) * nums[i].
Return the maximum possible total score by the time you reach the last index.

Example 1:

Input: nums = [1,3,1,5]
Output: 7
Explanation:
First, jump to index 1 and then jump to the last index. The final score is 1 * 1 + 2 * 3 = 7.

Example 2:

Input: nums = [4,3,1,3,2]
Output: 16
Explanation:
Jump directly to the last index. The final score is 4 * 4 = 16.

Constraints:

1 <= nums.length <= 105
1 <= nums[i] <= 105

Complexity Analysis

• Time Complexity: O(n)
• Space Complexity: O(1)
