    2600 - K Items With the Maximum Sum.

    Easy

    There is a bag that consists of items, each item has a number 1, 0, or -1 written on it.

    You are given four non-negative integers numOnes, numZeros, numNegOnes, and k.

    The bag initially contains:

    • numOnes items with 1s written on them.
    • numZeroes items with 0s written on them.
    • numNegOnes items with -1s written on them.

    We want to pick exactly k items among the available items. Return the maximum possible sum of numbers written on the items.

    Example 1:

    Input: numOnes = 3, numZeros = 2, numNegOnes = 0, k = 2

    Output: 2

    Explanation: We have a bag of items with numbers written on them {1, 1, 1, 0, 0}. We take 2 items with 1 written on them and get a sum in a total of 2. It can be proven that 2 is the maximum possible sum.

    Example 2:

    Input: numOnes = 3, numZeros = 2, numNegOnes = 0, k = 4

    Output: 3

    Explanation: We have a bag of items with numbers written on them {1, 1, 1, 0, 0}. We take 3 items with 1 written on them, and 1 item with 0 written on it, and get a sum in a total of 3. It can be proven that 3 is the maximum possible sum.

    Constraints:

    • 0 <= numOnes, numZeros, numNegOnes <= 50
    • 0 <= k <= numOnes + numZeros + numNegOnes
