Given A string s and a Dictionary of words dict, add spaces in s to construct a sentence where Each of the word is a valid dictionary word.Return all such possible sentences.For example, givens = "catsanddog" ,dict = ["cat", "cats", "and", "sand", "dog"] .A solution is ["cats and dog", "cat sand dog"] .The problem is word break's follow up. Now is not the time to judge whether or not to break, but to give all the break situations. If you use pure search+backtrack to be

Asked Question B in the middle, and I said the code was a little long and asked them to write it first) I found a small problem when I typed the B-question code. I asked them to write the F-question. I went to the next step and used the sample to create a diagram. I printed the code and found it wrong, The last few minor errors are found. After correction, the system submits and returns the TLE... After studying the questions carefully, I found that

This question is an enhanced version for finding the largest submatrix and the original matrix is a matrix ring that can be collusion between the top, bottom, and left. The original method is to copy the original matrix into four, then, the n * n matrix is used as the prototype to copy the mostThe large sub-matrix and the DP, but its complexity is O (n5). After the sub-matrix is handed in, TLE changes several to WA or

A long time ago, I heard that treap could write this question, and then watched the god code, and then ~ It is much easier to write than using splay. Here we need to change the method of treap. A normal treap maintains a weight value for each node and rotates it based on the weight value. In this way, we can divide a treap into two trees, the method is to create a useless node and then give the node an extremely powerful value. In this way, the node is the root node, and the left and right sub-v

HDU's fourth warm-up match is also the second group competition of vector. The late arrival of Victoria caused us to have a bad start (is that why we failed today? Haha) I read question I at the opening, and the result was not very good. In addition, I had a problem with the sample, and gave up and switched to G. Ted soon found question B relatively simple, decisive, someone will immediately pass B. Question B is a labyrinth problem, solving the minimum number of steps. Due to the suspension o

Question Question omitted. Analysis: I expanded the formula, pushed something out, enumerated digits, and then obtained an X, if X represents the number under the base where the current total number of digits minus one, the current number of digits is the minimum. After the write, TLE determines that it may take a long time. After reading other people's questions, I found my consideration complicated. In fact, this is a multiplication operation
