## Plus Minus in java

Given an array of integers, calculate the ratios of its elements that are positive, negative, and zero. Print the decimal value of each fraction on a new line.

#### Input Format

The first line contains an integer, N, the size of the array. The second line contains N space-separated integers of the array.

#### Output Format

Print the following 3 lines, each to decimals (use double in java):

proportion of positive values

proportion of negative values

proportion of zeros

#### Sample Input

```6
-4 3 -9 -5 4 1
```

```0.5
0.5
0
```

#### Explanation

There are 3 positive numbers, 3 negative numbers, and no zero in the array.

The proportions of occurrence are positive: 0.5, negative: 0.5 and zeros: 0.

In case you are solving in C++, setprecision to 3

## Solution:–

```import java.util.*;
import java.lang.*;
import java.io.*;

public class Main
{
public static void main (String[] args) throws java.lang.Exception
{
Scanner scanner = new Scanner(System.in);
int input = scanner.nextInt();
int arr[] = new int[input];
float positiveCount=0,negativeCount=0,zeroCount=0;

for(int i=0;i<input;i++)
{
int x = scanner.nextInt();
arr[i]=x;
}

for(int i=0;i<input;i++)
{
if(arr[i]>0)
{
positiveCount++;
}
else if(arr[i]<0)
{
negativeCount++;
}
else{
zeroCount++;
}
}

System.out.println((double)positiveCount/input);
System.out.println((double)negativeCount/input);
System.out.println(zeroCount/input);

}
}```
