I am really ashamed that I didn't find this. I already solved similar problems, so this should have been easy for me I'm ashamed I didn't think about it in contest time when I knew that Xn = pXn-1 + qXn-2. i am ashamed too, but just the opposite reason you are. i could NEVER solve this problem if y...

david,
you can check this input:

input wrote: 8
5 3
8 8

output wrote: 0 1

but your code outputs "failed" for this input.

check this input and output:

input wrote: 5 9
1 10
0 0

output wrote: 2 -1 1
1 0 1

i think these case you just swap x and y. but doing these, does the given equation ax+by=d satisfY?

i precalcuate the prime but did not precalculate the charmical number . i check every time. it is Accepted but it takes large time 1.450 sec. when i got n , i check whether it is prime or not. next check from 2 to n-1 if i got any other answer than a^n mod n= a, i break the loop. to calculate a^n mo...

sohel,
i Accepted this problem. But my program runs not so fast.

any way, i think you determine all path. You don't have to do that if you use shortest path algorithm. This can minimize your time enough.

check for this input and output:
input:

1
2
ab
abc

output:

• 3
  ab
  abc

CDiMa, i am very very interested about your Algorithm. would you please explain it more clearly. i can't recover your hints :oops: i have hardly managed to Accpeted this code within timelimit. My Accepted code run more than 6sec :roll: i have no knowledge how the other people solved this prolbem in ...

oh i forgot to say other things.

The initaial position of two people is adjecent of all the input data. ( i don't know if they are in same initial position or not. but i consider that case in my code. )

HI , RuiFerreira,

There is no test case such k=0;
and your outpur for your input mentioned earliar is same as my Accpeted code's output.


PS: i like your web site to compare two user . It's really nice

It is very annoying about the behavior of the judge for this problem 164. i got many WA and after that i have to read the board to do The backtracking as C-D-I and got ACC. isn't it silly? i just change some if-else statement's order. and also C-D-I is ordered when i backtrack , it is not actually t...

thanks all for replying me.

After rejudging the problem all of my previous WA got AC.

thanks again.

Noim, I was not sure if you had got accepted because of this sentence: Quote: first i have determined the lcs string for the input string and the reverse of input string---------> this is my quotation. This would give an LCS of abcd from abcdcbad, the lcs of abcdcbad and it's reverse string is NOT ...

Noim, did you get AC ? :wink: what do you think i give hints in this page, one year ago, without accepting the program?? look at my input statement of my ac program: scanf("%s", &input[1]); what do this prove? no need to see for a blank line. i don't think there is any meaningless input. Do you thi...

you can check for following input:

aaaab
abbbb
ababab
aaaaa
abbcdba
