You are given an integer array nums.

In one operation, you can select any prefix of nums and an integer $x$, then add $x$ to every element in that prefix.

Return the minimum number of operations required to make all elements in nums equal.

Constraints:

• $1 \leq$ nums.length $\leq 10^5$

• $-10^9 \leq$ nums[i] $\leq 10^9$
