B - Multi Test Cases

Score : $200$ points

Problem Statement

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:

``` $N$ $A_1$ $A_2$ $\dots$ $A_N$ ```

Output

Print $T$ lines. The $i$-th line should contain the answer for the $i$-th test case.

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 $2$.
