This function uses a list of values and their corresponding Roman numeral symbols to build the Roman numeral string iteratively. It starts with the largest value and keeps subtracting it from the input number until the number is reduced to zero, appending the corresponding symbols to the result string.		 passed

To solve this problem, we need to convert a given positive integer into its Roman numeral equivalent in lowercase. Roman numerals use a combination of symbols to represent values, with specific rules for subtractive combinations (e.g., 4 is "IV" instead of "IIII"). The solution involves mapping these values and their corresponding symbols, then iteratively constructing the result by subtracting the largest possible values from the input number.

### Approach
1. **Mapping Values to Symbols**: Create a list of tuples where each tuple contains a value and its corresponding Roman numeral symbol in lowercase. This list is ordered from the largest value to the smallest, including subtractive combinations (e.g., 900 as "cm", 400 as "cd", etc.).
2. **Iterative Construction**: For each value-symbol pair in the list, repeatedly subtract the value from the input number and append the corresponding symbol to the result until the value can no longer be subtracted. This ensures that the largest possible values are used first, adhering to the rules of Roman numeral construction.
3. **Result Construction**: Collect all symbols from the iterations and join them into a single string to form the final Roman numeral.

### Solution Code
```python
def int_to_mini_roman(number):
roman_numerals = [
(1000, 'm'),
(900, 'cm'),
(500, 'd'),
(400, 'cd'),
(100, 'c'),
(90, 'xc'),
(50, 'l'),
(40, 'xl'),
(10, 'x'),
(9, 'ix'),
(5, 'v'),
(4, 'iv'),
(1, 'i'),
]
result = []
for value, symbol in roman_numerals:
while number >= value:
result.append(symbol)
number -= value
return ''.join(result)
```

### Explanation
- **Mapping Values**: The list `roman_numerals` contains tuples of values and their corresponding Roman numeral symbols, ordered from highest to lowest. This includes subtractive combinations to handle cases like 4 (IV) and 9 (IX).
- **Iterative Subtraction**: For each value-symbol pair, the algorithm checks if the current number is greater than or equal to the value. If so, it appends the symbol to the result and subtracts the value from the number. This loop continues until the number is reduced to zero.
- **Efficiency**: The approach efficiently constructs the Roman numeral by always using the largest possible value first, ensuring correctness and adherence to Roman numeral rules. The use of a list to map values and symbols allows for straightforward iteration and symbol collection.

This method ensures that the Roman numeral is constructed correctly and efficiently, handling all values from 1 to 1000 as required.		 passed

wenxinyiyan To solve this problem, we can create a dictionary that maps integers to their corresponding Roman numerals. However, since the function requires the Roman numerals in lowercase, we'll store them in lowercase in the dictionary as well.

Here's the completed code for the `int_to_mini_roman` function:


```python

roman = ''
for value, numeral in roman_numerals.items():
while number >= value:
roman += numeral
number -= value

return roman
```
However, there's a small issue with the provided code and the examples. The examples use a non-standard Roman numeral system where `i` is subtracted from larger numerals to form smaller numerals (e.g., `iv` for 4, `ix` for 9, `xl` for 40, etc.). The standard Roman numeral system doesn't have numerals for numbers greater than 1000, and it doesn't subtract `i` from numerals larger than `v` or `x`.

Since the examples provided use this non-standard system, I'll assume that's what you're looking for. If you want to use the standard Roman numeral system, you'll need to adjust the code and examples accordingly.

With that in mind, here's the corrected code that matches the provided examples:


```python

1: 'i'

roman = ''
for value, numeral in sorted(roman_numerals.items(), reverse=True):
while number >= value:
roman += numeral
number -= value

return roman
```
Note that I added `sorted(roman_numerals.items(), reverse=True)` to ensure the dictionary items are processed in descending order of their values. This is necessary to correctly convert the number to Roman numerals using the subtraction principle.

Now, the function should produce the expected output for the provided examples:

### Explanation:
1. **Roman Numerals Mapping**: The `roman_numerals` list contains tuples of integer values and their corresponding Roman numeral symbols in lowercase.
2. **Result Initialization**: An empty string `result` is initialized to build the Roman numeral.
3. **Iteration and Construction**: The function iterates over the `roman_numerals` list. For each tuple, it checks if the current number is greater than or equal to the integer value. If so, it appends the corresponding symbol to `result` and subtracts the integer value from the number.
4. **Return Result**: Once the number is reduced to zero, the complete Roman numeral string is returned.

### Explanation:
- **Mapping (`val`)**: We have a list of tuples where each tuple contains an integer value and its corresponding Roman numeral. The list is ordered from the largest value to the smallest.
- **Loop**: We iterate through the list. For each tuple, we check if the number is greater than or equal to the integer value. If it is, we append the corresponding Roman numeral to the result list and subtract the integer value from the number.
- **Result**: After processing all the tuples, we join the list of Roman numerals into a single string and convert it to lowercase.

This approach ensures that the Roman numeral is constructed correctly and efficiently.		 passed
