Chen Tianqiao: Think of yourself as the forerunner of the Times Author of The Wall Street Journal: Loretta Chao This year's 34-Year-old flyover sometimes sees itself as the forerunner of the current era--at least for now, and Shanda Interactive Entertainment Limited (Shanda Interactive Entertainment Ltd.)

DescriptionWhile Mike is walking in the subway and all of the stuff in his back-bag dropped on the ground. There were several fax messages among them. He concatenated these strings in some order and now he has string s. He is not a sure if this is his own back-bag or someone else ' s. He remembered that there were exactly K messages in his own bag, each is a palindrome string and all tho SE strings had the same length.He asked him and tell him if he had worn his own back-bag. Check if th

The positive solution looks like a big mob search?First we consider that this is a binary graph, and it is easy to derive an algorithm after the network flow model is established.S-> line capacity is NUM[X]/2;Row-and-column capacity is 1 and requires (x, y) this point existsColumn->t capacity is NUM[Y]/2After we ran the network stream, we got a set of solutions.But we consider the output scenarioFor each row, if NUM[X] is an even number, then it is clear that the output scheme is correctBut if N

It's a simple question, but there's a bunch of disgusting boundaries.After gouging out the disgusting border:Suppose we know that the cyclic section on both sides is B1,B2Where H is the first time to reach the target is A1,A2And know that for the answer TT=a1+b1*t1=a2+b2*t2You can enumerate T1 to see if there is a viable solution.And because the LCM (B1,B2) began to circulate.and B1*b2So we enumerate the range of T1 in [0,mod]If there is no solution within this range, there must be no solution#i

/* The calculated ans[i] is the minimum value of the interval of continuous length I, but this minimum is the maximum of the interval length of all consecutive lengths I, if ANS[I+1] is larger than ans[i], then ans[i] can be updated to ans[i+1] because if i+ The maximum value of the minimum value of 1 consecutive number intervals is B, so the maximum value of the continuous number interval of length I can be achieved by removing one number. */for (i=n;i>=2;i--) {if (ans[i]>ans[i

Mike and FrogEnumeration.First, find the loop, and then it is easy to get a two-element equation, and then we can find that the solution also has a circular section, so the smallest one must appear within a certain range, otherwise it will not appear in the future. Assume that the two variables are x and y, and the coefficients are z1 and Z2. Obviously, the minimum public multiple of the two is

The original problem can be translated as: Given the K string, how many times it appears as a substring in the L-r stringDefines a suffix (nonsense) of a prefix of a substring to a stringis equivalent to inserting a string into the trie, where each passing node and its upward fail chain are substrings of that stringAnd because for a fail chain, U-up can access to v current only if u is in V's CoshineThen the original question becomes:Inserts a l-r string into trie as described above and incremen
