C++int change(int amount, vector<int>& coins) { vector<int> dp(amount + 1); dp[0] = 1; for (auto& coin : coins) { for (int i = coin; i <= amount; i++) { dp[i] += dp[i - coin]; } } return dp[amount]; } 分类: LeetCode 标签: 动态规划 好文要顶 关注我 收藏...
https://leetcode.cn/problems/coin-change-2leetcode.cn/problems/coin-change-2 之前做过一个题是零钱兑换,给定不同面额的硬币,找出最少需要多少个硬币,使得其面值等于amount。很容易找出dp状态转移方程为dp[i] = min{dp[i-coin_1], dp[i-coin_2], ... ,dp[i-coin_n]} + 1。本题跟上一题...
https://leetcode-cn.com/problems/coin-change-2/ Example 1: Input: amount = 5, coins = [1, 2, 5] Output: 4 Explanation: there are four ways to make up the amount: 5=5 5=2+2+1 5=2+1+1+1 5=1+1+1+1+1 Example 2: Input: amount = 3, coins = [2] Output: 0 Explanati...
for(状态1 in 所有取值){ for(状态2 in 所有取值){ dp[状态1][状态2] = 计算(选择1, 选择2) } } 下面解法使用了两种数组:一维数组、二维数组,一维数组更好理解,二维数组空间复杂度稍好,时间复杂度都是O(n*amount)
1. Coin Change- 1 Here you need to find the minimum number of coins needed to make the amount. We are choosing bottom-up approach here, which is mainly using arrays , 1d or 2d. We will initialise an array, say dp[] of size= amount+1. ...
