[讨论]出个题吧,DP...
典型的DP题
http://acm.hdu.edu.cn/showproblem.php?pid=2069


Problem Description
Suppose there are 5 types of coins: 50-cent, 25-cent, 10-cent, 5-cent, and 1-cent. We want to make changes with these coins for a given amount of money.

For example, if we have 11 cents, then we can make changes with one 10-cent coin and one 1-cent coin, or two 5-cent coins and one 1-cent coin, or one 5-cent coin and six 1-cent coins, or eleven 1-cent coins. So there are four ways of making changes for 11 cents with the above coins. Note that we count that there is one way of making change for zero cent.

Write a program to find the total number of different ways of making changes for any amount of money in cents. Your program should be able to handle up to 100 cents.

Input
The input file contains any number of lines, each one consisting of a number ( ≤250 ) for the amount of money in cents.

Output
For each input line, output a line containing the number of different ways of making changes with the above 5 types of coins.

Sample Input
11
26

Sample Output
4
13

让我很迷惑的是这句话
Your program should be able to handle up to 100 cents.

我觉得是"你的程序应该能够处理100美分内的情形"的意思

不过WA了N此后,发现似乎这句话的意思应该"你的程序应该处理硬币总数在100内的情形"

不过本人英语很烂,所以不排除是我的代码歪打正着的因素...

有点水,其实我就是想知道那句英语是怎么翻译的....

另外,如果雨中飞燕 把那个题目中的 <=250限制改到 <=10000出个题估计会好一点.

DP丫.
不过注意的是题目的要求:只考虑硬币总数在100内情形.
