// 322. 零钱兑换
//
// 给你一个整数数组 `coins` ,表示不同面额的硬币;以及一个整数 `amount` ,表示总金额。
// 计算并返回可以凑成总金额所需的 最少的硬币个数 。如果没有任何一种硬币组合能组成总金额,返回 `-1` 。
// 你可以认为每种硬币的数量是无限的。
// 示例 1
// 输入:coins = `[1, 2, 5]`, amount = `11`
// 输出:`3`
// 解释:11 = 5 + 5 + 1
// 示例 2
// 输入:coins = `[2]`, amount = `3`
// 输出:-1
// 示例 3
// 输入:coins = [1], amount = 0
// 输出:0
//
// 提示:
// - `1 <= coins.length <= 12`
// - `1 <= coins[i] <= 2^31 - 1`
// - `0 <= amount <= 10^4`
//
