You have some apples, where arr[i] is the weight of the i-th apple. You also have a basket that can carry up to 5000 units of weight. Return the maximum number of apples you can put in the basket. Example 1: Input: arr = [100,200,150,1000] Output: 4 Explanation: All 4 apples can be carried by the basket since their sum of weights is 1450. Example 2: Input: arr = [900,950,800,1000,700,800] Output: 5 Explanation: The sum of weights of the 6 apples exceeds 5000 so we choose any 5 of them. Constraints: 1 <= arr.length <= 10^3 1 <= arr[i] <= 10^3
