Run Details #822

Question: Write Python 3.12 code only. Define exactly one function named min_coins_for_amount(amount, coins). Return the minimum number of coins needed to make the amount exactly. If exact change is impossible, raise ValueError. Raise TypeError for invalid input types. Do not use any imports (no numpy, requests, or other libraries). Sandbox note: dunder attribute access is blocked (for example, type(x).__name__). Avoid names/attributes starting with '__'. Expected output format: - Return exactly one fenced Markdown code block starting with ```python and ending with ```. - Put only valid Python code inside that block (no prose before/after). - Use 4 spaces for indentation (not tabs). - Do not return JSON and do not wrap code in a "function" key. Sample input/output behavior: - min_coins_for_amount(44, [1, 4, 22]) -> 2 Task: Write a Python 3.12 function for making change with the fewest coins (e.g., 78c with 1c, 4c, 22c).

def min_coins_for_amount(amount, coins):
    if not isinstance(amount, int) or not all(isinstance(coin, int) for coin in coins):
        raise TypeError("Input types must be integers and lists of integers")
    elif amount < 0 or any(c <= 0 for c in coins):
        raise ValueError("All inputs must be positive integers")

    coins.sort()
    i = len(coins) - 1
    while amount > 0:
        if amount >= coins[i]:
            amount -= coins[i]
            i -= 1
        else:
            break

    return i + 1
