一个经典的贪心算法的简单例子是找零钱问题(Coin Change Problem)。假设你是一名售货员,需要找零给客户,而你手头有不同面额的硬币。你的目标是找零的硬币数量尽可能少。 假设你有 1 元、5 元、10 元、20 元和 50 元的硬币,现在需要找零 36 元。 贪心算法的思路是每次尽量使用面额最大的硬币,直到找零的总额...
Coin Change Problem 贪心证明 有i≤4,j≤1;也有l≤2(因为l一旦取3的话,就可以用一个k和一个j代替) 注意到l,j的两个不等式不能同时取到等号,若l=2,那么<<j=0,i+10l≤24<25,若j=1那么<<l≤1,i+5j+10l≤19<25;综上最优方案中,i+5j+10l≤24,所以我们一定会先一直取25的直到不能取了为...

The coin change problem is one of the popular coding interview question and knowing how to solve this problem can help you during coding interview. It's also useful to learn a couple of tricks and data structure. This problem somewhat has to do witharrays, so we shall be discussing what a...

By modeling the change in node representations during message propagation, we theoretically analyze the factors (e.g., degree, heterophily level) that make the representations of nodes from different classes indistinguishable. Our analysis highlights that (1) nodes with high heterophily and nodes ...
