Give me a python program for normalised Euclidean distance in INTITUTIONSITIC FUZZY SETS intitutionsitic fuzzy sets consit of membership value , non membership value ,hesitation degree.if we add membership value, non membership value and hesitation degree it give 1.The output as enter the membership value for IFS 1, enter the non membership value for IFS 1, enter the hesitation degree for IFS 1.enter the membership value for IFS 2, enter the non membership value for IFS 2, enter the hesitation degree for IFS 2.The normalised Euclidean distance= the final answer

Here's a Python program to calculate the normalized Euclidean distance between two Intuitionistic Fuzzy Sets (IFS). This program prompts the user to input the membership value, non-membership value, and hesitation degree for two IFS, and then it calculates the normalized Euclidean distance between them.

```python
import math

def input_ifs_values(ifs_number):
    print(f"Enter the values for IFS {ifs_number}:")
    membership = float(input("Enter the membership value: "))
    non_membership = float(input("Enter the non-membership value: "))
    hesitation_degree = float(input("Enter the hesitation degree: "))
    
    # Verify that the values add up to 1
    if not math.isclose(membership + non_membership + hesitation_degree, 1.0, rel_tol=1e-9):
        raise ValueError("The sum of membership, non-membership, and hesitation degree must equal 1.")
    
    return membership, non_membership, hesitation_degree

def calculate_normalized_euclidean_distance(ifs1, ifs2):
    # Calculate the squared differences for membership, non-membership, and hesitation degree
    squared_diff_membership = (ifs1[0] - ifs2[0]) ** 2
    squared_diff_non_membership = (ifs1[1] - ifs2[1]) ** 2
    squared_diff_hesitation = (ifs1[2] - ifs2[2]) ** 2

    # Calculate the Euclidean distance
    euclidean_distance = math.sqrt(squared_diff_membership + squared_diff_non_membership + squared_diff_hesitation)
    
    # Normalize the Euclidean distance
    normalized_distance = euclidean_distance / math.sqrt(3)
    
    return normalized_distance

def main():
    ifs1 = input_ifs_values(1)
    ifs2 = input_ifs_values(2)
    
    normalized_distance = calculate_normalized_euclidean_distance(ifs1, ifs2)
    
    print(f"The normalized Euclidean distance between the two IFS is: {normalized_distance:.4f}")

if __name__ == "__main__":
    main()
```

### Explanation:
- **Input**: The program asks for the membership value, non-membership value, and hesitation degree for two IFS.
- **Validation**: It checks that the sum of membership, non-membership, and hesitation degree equals 1.
- **Calculation**: 
  - Computes the squared differences for membership, non-membership, and hesitation degree.
  - Computes the Euclidean distance by summing the squared differences and taking the square root.
  - Normalizes this distance by dividing it by the square root of 3 (since there are three components: membership, non-membership, and hesitation).
- **Output**: The normalized Euclidean distance is printed.

### Example usage:
```
Enter the values for IFS 1:
Enter the membership value: 0.5
Enter the non-membership value: 0.3
Enter the hesitation degree: 0.2
Enter the values for IFS 2:
Enter the membership value: 0.4
Enter the non-membership value: 0.4
Enter the hesitation degree: 0.2
The normalized Euclidean distance between the two IFS is: 0.0816
```
