Problem Statement

Let’s take a prime P = 200\,003. You are given N integers A_1, A_2, \ldots, A_N. Find the sum of ((A_i \cdot A_j) \bmod P) over all N \cdot (N-1) / 2 unordered pairs of elements (i < j).

Please note that the sum isn't computed modulo P.

Constraints

  • 2 \leq N \leq 200\,000
  • 0 \leq A_i < P = 200\,003
  • All values in input are integers.

Input

Input is given from Standard Input in the following format.

N
A_1 A_2 \cdots A_N

Output

Print one integer — the sum over ((A_i \cdot A_j) \bmod P).


Sample Input 1

2019 0 2020 200002

Sample Output 1

474287

The non-zero products are:

  • 2019 \cdot 2020 \bmod P = 78320
  • 2019 \cdot 200002 \bmod P = 197984
  • 2020 \cdot 200002 \bmod P = 197983

So the answer is 0 + 78320 + 197984 + 0 + 0 + 197983 = 474287.
