WORD w[100000]; why is that array only 100000 big ? It's not neccesary to check out anymore !!!! Your observation is correct and exact, thanks !!!!! I increased length of array to 400000, and it was accepted :D. I didn't expect to have any wrong answer, because of using less memory than required. I...

Next code was the first one i submitted :D All later submissions are very similar. #include <stdio.h> int v[8][2] = {{-1,-1}, {-1,0}, {-1,1}, {0, -1}, {0, 1}, {1, -1}, {1, 0}, {1, 1}}; typedef struct { int cont; int isfinal; int letter[26]; } WORD; char map[101][101]; char words[15000][101]; WORD w[...

thanks angga888, but i'm still getting wrong answer :(. can anyone post their code of reading test cases of this problem, please ??? I've thought about no printable characters in map. problem is case sensitive ??? Thanks in advance. Maybe my algo is wrong :cry: . But i have faith in my code and algo...

Your assumption that the number of edges in such a graph is less than 3*V is wrong I have to accept you are allright. Very nice sample. When i solved this problem, i was thinking what was the worst case for number of triangules :D. Well, at least my algo runs on time. I didn't expect such a case. T...

Almost all of you are talking about fibonacci numbers. I found a formula that looks like: f(n) = c1 * f(n - 1) + f1(n-2); where f1 and f are functions totally diferent. But both depend on each other. I got it, using simple reasoning. Suppose we have all ways for connecting n - 1 houses. Let's try to...

Wow :o , nice solution. I solved this problem using brute force (Until now, without any optimization) Main idea is: Let X = Xn Xn-1 ... X1 be solution in base B. We start in this way: Define Yi(X1) as the most left digit of X1 * i in base B, then Yi(X1) = (X*i) % B; If there is a solution. Then it h...

A g-Gap is defined as a string in the form UVU such that |V| = g. For example: AALLAA is a 2-Gap taking U = AA and V = LL . furthermore is 4-GAP because of U = A and V = ALLA and |V| = 4, finally is not a 6-GAP, because U can not be empty. The problem consists in given a string S , and a positive in...

My programs runs is O(n^3) best case and O(n^4) in worst case. It runs in 1.059 seconds. Can anybody explain any O (n^3) solution ??? the circular can be solved by substracting the total of that column with minimum sum between row 1..n-2 -> therefore O(n^3) Maybe I am not a good english reader, but ...

### 10829 - L-Gap Substrings

Any hint for solving this problem ??

In the worst case (a string with 50,000 same character), the solution is greater than

I think, even using KMP's algrithm is not possible count all L-GAPs in time

Please, help.

**500,000,000**L-GAP. O.K. We can manage that case.I think, even using KMP's algrithm is not possible count all L-GAPs in time

I'm not sure if your algorithm is fast. In order to count the minimun number of swaps, you should use a 64-bit integer, because of in the worst case [ 500000, 499999, 499998, .... , 1 ] you need (500,000) * (499,999) / 2 swaps and that number doesn't fit into a 32-bit integer. My implementation use ...
