Hi I am getting verdict as "blank". What does it mean? I am waiting for more than 24 hours to get a verdict.

You have to use disjoint set forest algorithm. Or you can also use binary search tree. I think disjoint forest would be faster.

I had trouble getting it accepted. I did a funny thing. In stead of putting a newline character in between the outputs, I put it at the end of every output. And then it was accepted. It was funny because it could have shown presentation error instead of WA.

I am also wondering on this. I figured you got to read journal papers related to algorithms. I have some books which covers specialized algorithm such as bit manipulation, string matching(bio-informatics) and so on. I have also found a book on dynamic programming and greedy algorithm. Besides there ...

hmm. I found the bug. For 2 rather simple test cases:
accepted/accept
success/scs

I have a question. Any help would be greatly appreciated on this. I did straightforwardly for mapping team members to team. Like I created a big array with 1M entry, where the index is the member and array value is the team. What could be the elegant way to map this? I tried using bst for hashing bu...

what would be the output for

0 0?

would it be nothing or a blank line?

Jagadish's first set of input caused the uvatoolkit to break.

are there any more input sets to consider? I tried all the test cases posted here and seemingly the program passed.

I have this question: 500(3) 1000(4) 1100(5) 2000(9) 6000(2) 6000(6) 6000(8) 6008(1) 8000(7) 4000(4) 3000(5) 2100(2) 2000(3) 2000(6) 1900(9) 1400(7) 1300(1) 1200(8) Why is the answer not 4 5 2 6 7? 1000(4) 1100(5) 6000(2) 6000(6) 8000(7) 4000(4) 3000(5) 2100(2) 2000(6) 1400(7) If the answer can be o...

For the sample input/ouput sequence:

45 8 4 10 44 43 12 9 8 2

why is the solution not

43 2?

I tested this sequence (the permutation of the above):

45 8 43 2 4 10 44 12 9 8

with

http://uvatoolkit.com/problemssolve.php

and the output is coming out as

43 2

My problem is rather simple. I used the print_LCS from the cormen book: PRINT-LCS(b, X, i, j ) 1 if i = 0 or j = 0 2 then return 3 if b[i, j ] = “&” 4 then PRINT-LCS(b, X, i ? 1, j ? 1) 5 print xi 6 elseif b[i, j ] = “?” 7 then PRINT-LCS(b, X, i ? 1, j ) 8 else PRINT-LCS(b, X, i, j ? 1) and implemen...

That is a pretty cool site. But it still didn't work. The both outputs match (tested using diff -b). Still WA. I don't understand what else can remain. k can be >0, <0 and ==0. the polynomial can be degree 0, 1, 2, 3, 4. Upto degree 4 polynomial should be representative. That should be all. But what...

It seems like there are only 2 ways left to solve this:

1. beseech
2. bribe

if it were a girl instead then there would be a 3rd approach.

This is the code: #include <stdio.h> #include <string.h> #include <stdlib.h> #define MAX_DEGREE 20000 #define MAX_LEN 200000 char input[MAX_LEN]; int main() { int i; long a[MAX_DEGREE]; int k; int degree; long r; int j; long q[MAX_DEGREE]; long t; char* p; int n; char word[100]; int first = 1; // fr...
