Attention: In this version, the number of operations that can be performed, has been increased to twice. You are given an array nums consisting of positive integers. We call two integers x and y almost equal if both integers can become equal after performing the following operation at most twice: Return the number of indices i and j in nums where i < j such that nums[i] and nums[j] are almost equal. Note that it is allowed for an integer to have leading zeros after performing an operation.
