Complete the following erroneous code and add extra constraints:
/*
You are provided with a positive integer n. Your task is to create an integer array a with the length n.
For each i (1 ≤ i ≤ n), the value of a[i] = i * i - i + 1.
At this point, you are to implement a complex recursive function that equ... | codefeedback | [

Implement a computationally efficient algorithm to solve the following problem:
Given an array of integers, check if the sum of any two integers in the array is divisible by 10. The array may contain duplicates, and the algorithm should handle this properly.
