2558 - Take Gifts From the Richest Pile.

Easy

You are given an integer array gifts denoting the number of gifts in various piles. Every second, you do the following:

  • Choose the pile with the maximum number of gifts.
  • If there is more than one pile with the maximum number of gifts, choose any.
  • Leave behind the floor of the square root of the number of gifts in the pile. Take the rest of the gifts.

Return the number of gifts remaining after k seconds.

Example 1:

Input: gifts = [25,64,9,4,100], k = 4

Output: 29

Explanation: The gifts are taken in the following way:

  • In the first second, the last pile is chosen and 10 gifts are left behind.
  • Then the second pile is chosen and 8 gifts are left behind.
  • After that the first pile is chosen and 5 gifts are left behind.
  • Finally, the last pile is chosen again and 3 gifts are left behind.

The final remaining gifts are [5,8,9,4,3], so the total number of gifts remaining is 29.

Example 2:

Input: gifts = [1,1,1,1], k = 4

Output: 4

Explanation:

In this case, regardless which pile you choose, you have to leave behind 1 gift in each pile.

That is, you can’t take any pile with you.

So, the total gifts remaining are 4.

Constraints:

  • 1 <= gifts.length <= 103
  • 1 <= gifts[i] <= 109
