Sunny number
If given number + 1 is perfect square root means that is Sunny number.
Example-1:
Input : n = 3 Output : Sunny number Explain : 3 + 1 = 4 . The 4 is perfect square root so its "Sunny number".
Example-2:
Input : n = 4 Output : Not a Sunny number Explain : 4 + 1 = 5 . The 5 is not a perfect square root so its "Not a Sunny number".
Solution
public class Main
{
public static void main(String [] args)
{
int n = 3;
n = n + 1;
for (int i=1;i<=n;i++)
{
if(i*i==n)
{
System.out.print("Sunny Number");
break;
}
if(i*i>n)
{
System.out.print("Not a Sunny Number");
break;
}
}
}
}
import math
n = 3
a = n+1
b = math.sqrt(a)
if(b**2==a):
print("Sunny number")
else:
print("Not a sunny number")
Output
Sunny Number
