}; | | good idea to avoid mistake | Celebrate | 1575. Екатеринбургское метро 2 | 8 окт 2021 04:45 | 1 | I have some mistake in the staion name which I can't find it in my code.
Then I search all the string my write and calculate LCS.
The string has maximal LCS is what we want to find.
Like that:
int __(string ss){
if(f.find(ss)==f.end()){
int ans=0,pos=0;
rep(ki,1,cnt){
mst(dp,0);
for(int i=1;i<=ss.length();i++){
for(int j=1;j<=s[ki].length();j++){
if(ss[i-1]==s[ki][j-1])dp[i][j]=dp[i-1][j-1]+1;
else dp[i][j]=max(dp[i-1][j],dp[i][j-1]);
}
}
if(dp[ss.length()][s[ki].length()]>ans)ans=dp[ss.length()][s[ki].length()],pos=ki;
}
return pos;
}
return f[ss];
}
Then I got AC from wa2

With the given memory contraints, you can doit like that. | | Something really strange... | Vedernikoff Sergey | 1575. Екатеринбургское метро 2 | 24 май 2013 00:04 | 5 | It seems that my program gives right answers to all tests, but, nevertheless, WA #2 :((( 1)check better names
2)find all distance
1 - 2
1 - 3
....
69 - 70
and after try find a b c
L[a,b] + L[b,c] < L[a,c]
P.S. if 1 and 2 correct check you constans But I have WA #2. All constants are correct, and I use Floyd-Worshall to find all distances. Mysterious WA...
Edited by author 26.10.2008 21:06 Did you find the problem? I also use Floyd-Warshall, but WA2. | | It is very easy problem just Floyd algo,or BFS,or Dijsktra but WA#2,help please | Hrayr | 1575. Екатеринбургское метро 2 | 21 июн 2011 21:33 | 1 | Now AC!!!!!!!!!!!!!
And this for everybody.
1) check them names
2) check the graph
3) check the station indexes
if everything is OK you'll get AC.
Edited by author 21.06.2011 23:24 | | why there is a string in test#2 doesn't show up in the map ? | William Chou | 1575. Екатеринбургское метро 2 | 20 фев 2011 12:15 | 3 | I insert all string that show up in the map into index (std::map<string,int> index).
And I use these code to debug:
string s1,s2;

if (index.find(s1) == index.end() || index.find(s2) == index.end())
while (true);//if the string doesn't show up in the map,I will get TLE.

Who can help me?
Thanks.
Sorry for my poor English.
PS:It's guarantee that I won't insert wrong string into index.

1st is yellow-red
2nd is purple-green
and there is no transition between them! Am i right? Then stations (graph vertices) count to 71. And the path from
"Shevchenko" to "1905_year_square" is 1 or 2 depending where we go!
So, i also have WA#2 and think maybe here is my fault... No, you are wrong. 1905_year_square is an intersection of 4 lines: yellow, red, purple and green. Yes, thanks.
But the picture is tangling. Two-colored circles must have suggested that there is a transition between two stations if there exists a circle with sectors of the two colors. This condition is true everywhere except 1905_year_square.
On the other hand, there is no circle where yellow and green branches come and outcome together (what could be another intuitive criteria). So there is no reason to consider the two disputable circles as one station but their nearness. | | WA2 | Lebedev_Nicolay[Ivanovo SPU] | 1575.
