# Minimum Replacements to Sort the Array LeetCode Solution

## Problem – Minimum Replacements to Sort the Array LeetCode Solution

You are given a 0-indexed integer array `nums`. In one operation you can replace any element of the array with any two elements that sum to it.

• For example, consider `nums = [5,6,7]`. In one operation, we can replace `nums` with `2` and `4` and convert `nums` to `[5,2,4,7]`.

Return the minimum number of operations to make an array that is sorted in non-decreasing order.

Example 1:

``````Input: nums = [3,9,3]
Output: 2
Explanation: Here are the steps to sort the array in non-decreasing order:
- From [3,9,3], replace the 9 with 3 and 6 so the array becomes [3,3,6,3]
- From [3,3,6,3], replace the 6 with 3 and 3 so the array becomes [3,3,3,3,3]
There are 2 steps to sort the array in non-decreasing order. Therefore, we return 2.``````

Example 2:

``````Input: nums = [1,2,3,4,5]
Output: 0
Explanation: The array is already in non-decreasing order. Therefore, we return 0.``````

Constraints:

• `1 <= nums.length <= 105`
• `1 <= nums[i] <= 109`

### Minimum Replacements to Sort the Array LeetCode Solution in C++

``````    long long minimumReplacement(vector<int>& A) {
long n = A.size(), x = 1e9, res = 0, k;
for (int i = n - 1; i >= 0; --i) {
k = (A[i] + x - 1) / x;
x = A[i] / k;
res += k - 1;
}
return res;
}
``````

x = A[-1]
res = 0
for a in reversed(A):
k = (a + x - 1) // x
x = a // k
res += k - 1
return res
