Hey guys,

so I'm doing some assignments in the R programming language, and I think it's kinda similair to java so hoping to get help here.

Suppose you have a random set of numbers, say 's <- c(1,5,4,2)'
How would I print out all odd numbers the integer way?

I can do it using booleans, like this:
s[lapply(s, "%%", 2) != 0]

But how would I do it using integers?
Obviously, s[c(1,2)] wouldn't work because if the set of number changes, it doesn't hold anymore.

Help would be appreiciated!

in java:
int[] arr = new int[]{1,5,4,2};

for(int i=0; i<arr.length; i++){
System.out.print(arr[i] * (arr[i]%2));
}

you cant make decisions without using booleans so it will print 0 if the number was even.
not really sure if that is what you wanted but it will print all odd numbers and will print 0 if the number was even
you would have to use a boolean to filter out the even numbers completely.

Code

public class oddInt
{
    public static void main(String[] args)
     {
          int[] array = new int[]{5,2,4,6,1,3, 9, 7 ,3, 23,43,1,2,34,5,6,7,10};
          for(int i = 0; i < array.length; i++)
          {
               if(array[i] % 2 != 0)
               {
                    System.out.println(array[i]);
               }
      }
}

}

Output:
5
1
3
9
7

23
43
1

public class oddInt
{
    public static void main(String[] args)
    {
         int[] array = new int[]{5,2,4,6,1,3, 9, 7 ,3, 23,43,1,2,34,5,6,7,10};
         for(int i = 0; i < array.length; i++)
         {
              if(array[i] % 2 != 0)
              {
                   System.out.println(array[i]);
              }
     }
}

}

Output:
5
1
3
9
7
3
23
43
1
5
7

You can also use this since Java 8:

Code

public class OddInt {
   public static void main(String[] args) {
       int[] array = {5, 2, 4, 6, 1, 3, 9, 7, 3, 23, 43, 1, 2, 34, 5, 6, 7, 10};
       Arrays.stream(array).filter(x -> (x % 2 != 0)).forEach(System.out::println);
   }
}

Looks more sexy to me to do it in a functional style, and streaming can also boost performance
