Solution: Final Array State After K Multiplication Operations I

Understand how to use min heaps to repeatedly identify and multiply the minimum element in an array k times. This lesson teaches you to implement a solution that updates the array efficiently by leveraging a heap structure to maintain order and achieve optimal time complexity.

We'll cover the following...

Statement

Given an integer array nums, an integer k, and an integer multiplier:

  • Perform k operations on nums.

  • In each operation:

    • Find the minimum element x in nums (if there are multiple occurrences of the minimum value, choose the first occurrence).

    • Replace x with x * multiplier.

Return the final state of nums after all k operations.

Constraints:

  • 1<=1 <= nums.length <=100<= 100 ...
