3180 - Maximum Total Reward Using Operations I.

Medium

You are given an integer array rewardValues of length n, representing the values of rewards.

Initially, your total reward x is 0, and all indices are unmarked. You are allowed to perform the following operation any number of times:

• Choose an unmarked index i from the range [0, n - 1].

• If rewardValues[i] is greater than your current total reward x, then add rewardValues[i] to x (i.e., x = x + rewardValues[i]), and mark the index i.

Return an integer denoting the maximum total reward you can collect by performing the operations optimally.

Example 1:

Input: rewardValues = 1,1,3,3

Output: 4

Explanation:

During the operations, we can choose to mark the indices 0 and 2 in order, and the total reward will be 4, which is the maximum.

Example 2:

Input: rewardValues = 1,6,4,3,2

Output: 11

Explanation:

Mark the indices 0, 2, and 1 in order. The total reward will then be 11, which is the maximum.

Constraints:

• 1 <= rewardValues.length <= 2000

• 1 <= rewardValues[i] <= 2000
