README ¶ 322. Coin Change [中等] 动态规划 给定不同面额的硬币 coins 和一个总金额 amount。编写一个函数来计算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 示例 4: 输入:coins = [1], amount = 1 输出:1 示例 5: 输入:coins = [1], amount = 2 输出:2 提示: 1 <= coins.length <= 12 1 <= coins[i] <= 231 - 1 0 <= amount <= 104 Expand ▾ Collapse ▴ Documentation ¶ There is no documentation for this package.
