    int i,len=0;
     gets(str0);
      for(i=0;str0[i]!='\0';i++,len++)  str1[i]=str0[i]-'a';

       str2[0]=str1[0];
       for(i=1;i<len;i++)
       {  str2[i]=str1[i];
         while(str2[i]<str2[i-1])
        {   str2[i]+=26;

         }
       }

        str3[0]=str2[0]-5;
        for(i=0;i<len;i++)
        str3[i+1]=str2[i+1]-str2[i];

       for(i=0;i<len;i++)
         printf("%c",(str3[i]%26)+'a');

What is wrong with test 4?

/// What's wrong?
var a,b,c,i,s:integer;
m:array[1..1000000] of integer;
begin
s:=0;
read(a);
read(b);
for i:=1 to b do
begin
read(m[i]);
if(m[i]>a) then
s:=s+m[i]-a
else
begin
if s>m[i]+a then
s:=s-m[i]-a
else
s:=0;
end;
end;
if s<0 then writeln(0)
else writeln(s);
end.

Sorry for my poor english.
I run code on my pc with different params. Where may be error? Test alltime is wrong. See screenshot: http://rghost.ru/59087997/image.png

Дайте тест №2, ну или все тесты на эту задачу!!!

Please don't make so stupid mistakes that I did. Lost about 3 hours on the contest, gratz to me.

Answer: oo

it's very simple,especially on java.

The order of 1's within the number is 1 2 4 7 11 16 ...You can find the n'th number in sequence is equal to 1+n*(n-1)/2. So for any given input a, it is sufficient to test whether or not (a-1)*2 is equal to multiplication of two consequence number. I hope it helps

What is test case 4? please help

var n,i: integer;
x1,x2,y2,y1,xx,yy,e,r: real;
begin
 readln(n,r);
 readln(x1,y1);
 yy:=y1; xx:=x1;
 for i:=2 to n do
  begin
   readln(x2,y2);
   e:=e+sqrt(sqr(x2-x1)+sqr(y2-y1));
   x1:=x2; y1:=y2;
  end;
writeln((round((e+2*3.14159*r+sqrt(sqr(xx-x1)+sqr(yy-y1)))*100))/100);
end.

I'm using Heavy light Decomposition an I'm getting ML in test 9 WHY ????

I use fgets to read from stdin, when I try to store name in an array with length 201, i got WA 3,but when I changed the length to 210, I got AC, who can tell me why?

Hi,
This is my code:

#include <iostream>
#include <vector>
#include <cmath>
#include <iomanip>

using namespace std;

int main()
{
vector<int> V;
V.resize(0);
int n;

cin >> n;
while( n != EOF) {
    V.resize(V.size() + 1);
    V.push_back(n);
    cin >> n;
}

cout << setprecision(4) << fixed ;
while(V.size() > 0) {
n  = V.back();
V.pop_back();
cout << sqrt(n) << endl;
}

return 0;
}

Could someone please tell me why the memory got exceeded here ? The stream is just 256 KB, right ?

Regards,
Ankita
