Given a number the task is to find the frequency of even digits present in that number.
Example: Consider a number 256225. Here 2 is present three times, 6 is present one time. We will not consider 5 since it is not an even number.
Java
import java.util.*;
public class EDFrequency
{
public static void main(String args[])
{
int n=0,r=0,frequency=0,nCopy=0;
Scanner sc=new Scanner(System.in);
System.out.print("Enter a number: ");
n=sc.nextInt();
nCopy=n;
System.out.println("Digit\tFrequency");
for(int i=0;i<=9;i++)
{
n=nCopy;
while(n>0)
{
r=n%10;
if(r==i&&r%2==0)
{
frequency++;
}
n=n/10;
}
if(frequency>0)
{
System.out.println(i+"\t"+frequency);
}
frequency=0;
}
}
}
