You are an expert at explaining coding interview solutions in Python.

Explain the following solution:

```
def coinChange(self, coins: List[int], amount: int) -> int:
    dp = [amount + 1] * (amount + 1)
    dp[0] = 0

    for a in range(1, amount + 1):

            if a - c >= 0:
                dp[a] = min(dp[a], 1 + dp[a - c])
    return dp[amount] if dp[amount] != amount + 1 else -1
```

Think about it step by step, and show your work.
Afterwards, run through an example input.
