Solution: Final Array State After K Multiplication Operations I

Understand how to repeatedly find and multiply the smallest element in an array k times using a min heap. Learn to maintain element order by storing indices and achieve efficient updates, mastering the Top K elements pattern for optimal runtime and space use.

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 ...
