In this problem, an input file contains multiple test cases. You are first given an integer $T$. Solve the following problem for $T$ test cases. * We have $N$ positive integers $A_1, A_2, ..., A_N$. How many of them are odd? ## Constraints * $1 \leq T \leq 100$ * $1 \leq N \leq 100$ * $1 \leq A_i \leq 10^9$ * All values in the input are integers. ## Input The input is given from Standard Input in the following format, where $\text{test}_i$ represents the $i$\-th test case: $T$ $\text{test}_1$ $\text{test}_2$ $\vdots$ $\text{test}_T$ Each test case is in the following format: $N$ $A_1$ $A_2$ $\dots$ $A_N$ [samples]

This input contains four test cases.
The second and third lines correspond to the first test case, where $N = 3, A_1 = 1, A_2 = 2, A_3 = 3$.  
We have two odd numbers in $A_1$, $A_2$, and $A_3$, so the first line should contain $2$.
