You are given an integer array nums.

A pair of indices $(i, j)$ is considered a perfect pair if $0 \leq i < j <$ nums.length and the following two conditions are satisfied for $a =$ nums[i] and $b =$ nums[j]:

1. $\min(|a - b|, |a + b|) \leq \min(|a|, |b|)$

2. $\max(|a - b|, |a + b|) \geq \max(|a|, |b|)$

Return the total number of perfect pairs in nums.

Constraints:

• $2 \leq$ nums.length $\leq 10^5$

• $-10^9 \leq$ nums[i] $\leq 10^9$
