测试常见算法面试题:贪心法--找零问题 贪心算法(Greedy Algorithm): 贪心算法是一种基于局部最优选择来构建全局最优解的算法。它通常适用于那些可以通过一系列局部最优选择来达到全局最优解的问题。贪心算法每一步都会做出当前看起来最佳的选择,而不考虑未来的后果是否最优。经典的贪心算法包括霍夫曼编码、最小生成树...
The Coin Changing problem The Coin Changing problem动态规划完美解决硬币找零问题
has six coins: two quarters, onedime, a nickel, and two pennies.• We can use a greedy algorithm to solve this problem:repeatedly choose the largest coin less than or equal to theremaining sum, until the desired sum is obtained.• This is how millions of people make change every day...
Recall the coin change problem - using a set of denomination, we try to use greedy to pay a change amount using a minimum number of coins. We know from the lecture, some denominatios work, some do not. For example, greedy algorithm ...

The Change-Making Problem is to represent a given value with the fewest coins\nunder a given coin system. As a variation of the knapsack problem, it is known\nto be NP-hard. Nevertheless, in most real money systems, the greedy algorithm\nyields optimal solutions. In this paper, we study...
