Digit Frequency Validation

Write a Python function `validate(n)` that takes an integer `n` as input and checks whether the frequency of each digit in the integer is less than or equal to the digit itself. The function should return `True` if the condition is met for all digits, otherwise `False`.

#### Example Usage
```python [main.nopy]
validate(1234)  # True, as no digit appears more times than its value.
validate(51241) # False, as digit '1' appears twice, which is more than its value.
validate(321)   # True, as all digits satisfy the condition.
```

#### Constraints
- The input integer `n` can be positive or negative.
- The function should handle integers with multiple digits.
def validate(n):
    """
    Check whether the frequency of each digit in the integer is less than or equal to the digit itself.

    Args:
        n (int): The input integer.

    Returns:
        bool: True if the condition is met, False otherwise.
    """
    # Convert the integer to its absolute value to handle negatives
    n = abs(n)
    # Placeholder for the solution
    pass
