Maximum Number of Products You Can Pick
You have an array of products, where each element contains how much product you have
products = [2, 9, 4, 7, 5, 3]. Pick a subarray of products. Starting from the
beginning of the subarray, pick some number of products. One restriction: the number of products
you pick have to be strictly increasing.
For example, you choose [7, 5, 3], you pick 4 products out of 7, 5 out of 5, there's
nothing to pick from [3]. But you can pick [1, 2, 3], a total of 6 products.
The ask is to find the maximum number of products you can pick. The answer for the above example is 16.
Because you pick [2, 9, 4, 7] subarray and [2, 3, 4, 7] products out of it.
Constraints:
1 <= len(products) <= 5000the array length won't exceed 50001 <= products[i] <= 10^9, the stocks per product won't exceed 10^9
Complete the function maximumProductsPicked in the editor.
maximumProductsPicked has the following parameter:
int[] products: an array of integers representing the stock of each product
Returns
int: the maximum number of products you can pick
1Example 1
The optimal subarray to pick from is [2, 9, 4, 7]. You can pick the following number of products:
- From the first product: 2
- From the second product: 3 (since it must be strictly more than the previous pick)
- From the third product: 4 (since it must be strictly more than the previous pick)
- From the fourth product: 7 (since it must be strictly more than the previous pick)
2 + 3 + 4 + 7 = 16.
