Question

Question 9 (10 points) Suppose an array of integers is considered "special" if it contains more multiples of 3 than multiples of 5. Note that the same number may be both a multiple of 3 and a multiple of 5. For example, the array {3, 15, 10] is not special because it contains two multiples of 3 (3, 15) and also two multiples of 5 (15, 10). Write a method that takes an array of integers as a parameter and returns whether the array is "special" according to this definition. Be sure to include the full method header. Do not include the class or main method, and do not read any user input.

Answer 1

CODE TO COPY:

METHOD:

public static boolean checkSpecial(int arr[])
{
int[] count=new int[2];   
int n=arr.length;
for(int i=0;i<n;i++)
{
if(arr[i]%3==0)
{
count[0]++;
}
if(arr[i]%5==0)
{
count[1]++;
}
}
if(count[0]>count[1])
{
return true;
}

else{
return false;
}

}
  

FULL EXPLANATION OF THE CODE INCLUDING MAIN:

1 import java.util.Scanner; 2 public class Main 3 - { public static boolean checkSpecial(int arr[]), int[] count=new int[2]; int n=arr.length; for(int i=0;i<n;i++) { if(arr[i]%3==0) // array 'count' of type integer is decalred with size 2 // integer 'n' WHICH IS ASSIGEND LENGTH OF ARRAY // for Loop // checks if the element at index is divisible 3 { count[@]++; // if yes, increment the value of count[@] by 1 // checks if the element at index i is divisible by 5 if(arr[i]%5==0) count[1]++; // if yes, increment the value of count[1] by 1 if(count[@]>count[1]) I if count[e] i.e, no. of elements divisible 3 is greate than count[1](no. of elements divisible by 5) return true; // then return true else{ return false; // else return false

31 - public static void main(String[] args) { int [] arr=new int[6]; Scanner sc=new Scanner(System.in); // arr is declared with size 6 for(int i=0;i<4;i++) arr[i]=sc.nextInt(); //initialization of array..reads elements for array boolean value=checkSpecial(arr); // returned value(i.e, true or false) is assigned to variable 'value' if(value) 43. // if value is true System.out.println("Special"); // the print special else{ System.out.println("Not Special"); // otherwise not speciali 48 49 50 ]

OUTPUT:

3 10 24 18 Special
