number of questions in the group according to the size of the two parts, all negative numbers in the front of all non-negative, how to do?If we change the subject, we can divide the number of the array into two parts, and the number divisible by 3 is in front of the number that cannot be divisible by 3. What to do?This is where the interviewer is examining our understanding of extensibility. It is hoped that we can give a pattern in which the existing solution can be extended to the same type o

Refer to the Print method.Summary: This approach is easier to understand. can also adapt to arbitrary length of the problem of the subset.According to this approach, another problem can be solved--01 knapsack problem (There are five items numbered a,b,c,d,e respectively. Their weights are 2,2,6,5,4, and their value is 6,3,5,4,6. Now give you a backpack with a weight of 10. How to make the items loaded in the backpack have the maximum value sum?

Even if I can't understand the sentence (the stale translation), I'll fold it up so that I can sweep it two times. To tell the truth, it is still very fulfilling to read.ButReview: Like a nightmare!The generic parts of terror, painful examples, stale Chinese translations, lengthy descriptions.It was really painful, the generic
