Input : n=2021 Output : Duck Number Explain : The number 2021 have zero in between the number. So the number is called "Duck Number".
Example-2:
Input : n=2340 Output : Duck Number Explain : The number 2340 is ends with zero. So the number is called "Duck Number".
Example-3:
Input : n=0025 Output : Not a Duck Number Explain : The number 0025 exact value is 25 and Its not have Zero. So Its not a Duck Number.
Example-4:
Input : n=2345 Output : Not a Duck Number Explain : The number 2345 is not have zero.So It's not a Duck Number.
Example-5:
Input : n=023045 Output : Duck Number Explain : The number 023045 exact value is 23045 and Its have zero. So it's Duck Number.
Solution
public class Main
{
public static void main(String [] args)
{
int n=2020;
while(n!=0)
{
if(n%10==0)
{
System.out.print("Duck Number");
break;
}
n=n/10;
if(n==0)
{
System.out.print("Not a Duck Number");
}
}
}
}
n=2021
n=str(n)
n=n.lstrip("0")
if("0" in n):
print("Duck number")
else:
print("Not a Duck number")
Output:
Duck Number
