Bug Report for https://neetcode.io/problems/coin-change

In the Test Case coins=[2], amount=3, it passed during the first run, but after submission, it didn't work.

I even ran it locally and it gives the correct result

Here's My Solution:

class Solution:
    dp = {}
    def coinChange(self, coins: List[int], amount: int) -> int:
        if amount < 0:
            return -1
        
        if amount == 0:
            return 0
        
        result = 2147483647
        for c in coins:
            if amount - c >= 0:
                if not (amount - c) in self.dp:
                    self.dp[amount - c] = self.coinChange(coins, amount - c)
                
                if self.dp[amount - c] == -1:
                    continue
                
                result = min(self.dp[amount - c] + 1, result)
        
        return -1 if result == 2147483647 else result
