Minimum Replacements to Sort the Array
Explore how to solve the problem of sorting an array with the fewest operations by splitting elements into sums using greedy techniques. Understand the challenge of making an array non-decreasing through minimal replacements and implement efficient solutions in code.
We'll cover the following...
Statement
You are given a 0-indexed integer array nums. You are allowed to perform the following operation any number of times:
Select any element in the array and replace it with two positive integers whose sum is equal to the selected element.
For example, if the array is nums = [5, 6, 7], you can choose the element 6 and replace it with 2 and 4, resulting in a new array [5, 2, 4, 7].
Your goal is to make the array sorted in non-decreasing order using the minimum number of operations.
Return the minimum number of operations required to achieve this.
