What is your problem?

I think your program get SigSeg somewhere and so, it got TLE. Try to replace memset with a for loop which set all the elements of an array. I am not sure about how memset in C/C++ do.

try to change
char lCase1[1001] = {0,};
char lCase2[1001] = {0,};
In checkMap, you go till a 0 is meeted, what if the inputs string's length are exactly 1000. you missed the trailing 0.

Let T(n,s) be the number of cases in which sum of n numbers (all less than 10) are eqaul to S. It is not hard to find a recursive descripton for T(n+ 1,s). Let T(n,s) be the number of cases in which sum of n numbers (all less than 10) are eqaul to S and the first number is non-zero. T'(n,s) can be e...

one of your code problem is that num must be longint,
because, the problem states that n<1000000000.

dear Riyad I dont think your code has any chance for getting accepted :wink: becuase you want to avoid having 0 by using , mult=mult%100000; which when i> 100000 , for example i=1000000> 20000000 then mult will be 0 and ... also in your while where x= mult%10, i cant understand why you use a loop, ?...

hi every one.
could you please tell me what is output for the following input
1

a
ab
abc
abd
abcd

is it
a
.ab
..abc
..abd
..abcd

or

a
.ab
..abc
..abd
...abcd <-

thanks
Amir

hi dear i afraid your program has problem with n> 100. that is correct that i^i= (i+ 100)^ (i+ 100) but note that you want to calculate the sum of this numbers. so i think you must at first find the last digit of (n div 100) (call it as a) and also n mod 100 (and call it as b). and let c and d be c:...

dear htl
consider the case where m has a prime factor which is bigger than Sqrt (2^31).
i think in these cases your code is wrong

hi to all pascal lover! I looking for an IDE in linux to compile and and debug my pacal programs. I searched a lot but I can't find anything usefull except one IDE in FreePascal home page. but I can't compile it because it needs to a unit that isn't available for public. After sometime I found RhIDE...

hi

if you read the problem more carefully, you can see that the problem says , |L- U|< 1000000.
i means that you must do Sieve of Eratosthenes on an array with maximum length of 1000000.

may be your problem is in log function ( i mean that floating point error). why you don't devide a by n in your while and check if new a is a devisor of n. something like this: i:= 0; while (a mod n= 0) do begin Inc (i); No := a div n; a:= a div n; end; if a= 1 then for i:= 1 to i do Write (No ) els...

Dear Shamim
As I know there is n't any polynominal time alg for graph vertex coloring,
and this problem could be converted to a vertex coloring problem!!
I cant understand what do you mean by an alg les than O (n2).

Dear Adrian Kuegel
I think I solve the problem correctly but getting WA.
I want to know what is the lower point of the board. is it (0, 0) or (1, 1) or no limit?
thnx

hi to all,
i want to know if there is any object pascal compiler in linux.
as you know BP 7.0 supports object pascal and we can define class in it.
i search the web but i cant find anything (maybe because of wrong keyword in search).
thanks for your help.
