Maximum Product After K Increments
To achieve the maximum product after at most k
operations, we need to increment the smallest values in the array nums
. The simplest approach to do this is to use a minheap to keep track of the smallest values and increment them until we have used all k
operations.
Here’s the code to do this:


This code first transforms the nums
list into a minheap, so that the smallest value can be efficiently accessed and updated. Then it performs k
increments on the smallest values in the heap, and finally calculates the product, taking the modulo as required.
The time complexity of this solution is (O(k \log n)), where (n) is the length of the nums
array, as there are (k) increments, and each operation on the heap takes (O(\log n)) time.
