题目描述
Shaun is very much interested in Subarrays. Shaun wants to count the number of subarrays in his chosen array with sum being a multiple of $10^9$. Since, Shaun is interested in huge numbers.He chose his array such that it contains only $10^8$ and $9*10^8$ as its elements.
Help shaun to count the number of required subarrays.
-----Input:-----
- First line will contain $T$, number of testcases. Then the testcases follow.
- First line of each testcase contains one integer $N$,size of array $A$.
- Second line of each testcase contains $N$ space separated array elements
-----Output:-----
For each testcase, output in a single line number of subarrays with sum being multiple of $10^9$.
-----Constraints-----
- $1 \leq T \leq 10$
- $1 \leq N \leq 10^5$
- $A[i]$=$10^8$ , $9*10^8$
