In the below program, input is an array l[] that represents lengths of words in a sequence. The value l[i] indicates length of the ith word (i starts from 1) in theinput sequence. http://www.geeksforgeeks.org/dynamic-programming-set-18-word-wrap/ 另外可以参考wiki的这篇:https://zh...
1) Abinomial coefficientC(n, k) can be defined as the coefficient of X^k in the expansion of (1 + X)^n. 2) A binomial coefficient C(n, k) also gives the number of ways, disregarding order, that k objects can be chosen from among n objects; more formally, the number of k-ele...
Today I've listed some DP tutorials and problems. Actually, I made it for my personal practice. But I think It may Help others too. Update: I write stuffHerein Bengali. I probably have one or two basic DP tutorials too. If you understand Bengali, it may help. ...

The above solution may try all subsets of given set in worst case. Therefore time complexity of the above solution is exponential. The problem is in-factNP-Complete(There is no known polynomial time solution for this problem). We can solve the problem inPseudo-polynomial timeusing Dynamic prog...
