Write an iterative/recursive function in **Python** to check whether the number taken as function argument is Adam Number or not.

Definition: **Adam Number** is a number which when reversed, the square of the number and the square of the reversed number should be numbers which are which are reverse of each other.

**Examples**: Adam Numbers up to 1000 are 0, 1, 2, 3, 11, 12, 13, 21, 22, 31, 101, 102, 103, 111, 112, 113, 121, 122, 201, 202, 211, 212, 221, 301, 311.

13 is Adam Number because 13^{2} = 169.

Reverse of 169 = 961.

√961 = 31, which is the reverse of the original number 13.

```
def isAdam(num):
n = num
rev = 0
while n != 0:
rev = rev * 10 + n % 10
n = n // 10
sn = num ** 2
sr = rev ** 2
n = sr
rev = 0
while n != 0:
rev = rev * 10 + n % 10
n = n // 10
return sn == rev
num = int(input("Enter the number: "))
if isAdam(num):
print(str(num) + " is an Adam Number.")
else:
print(str(num) + " is NOT an Adam Number.")
```
