I don't understand, where I made a mistake, but program crushes there everytime, although in my compilator it is works

judje saied my solution does not work correctly on #3 and i do not know what is #3
but i think my code works correctly

program timus_1100;
const
  maxn=150000;
var
  ID:array[1..maxn]of longint;
  np:array[1..maxn]of byte;
  n:longint;
  i,j:longint;
begin
  readln(n);
  for i:=1 to n do
    readln(ID[i],np[i]);
  for i:=100 downto 0 do
    for j:=1 to n do
      if np[j]=i then
        writeln(ID[j],' ',np[j]);
end.

Program is in Java 1.8 but gives wrong answer on the timus server. Any help will be appreciated. Thanks a lot.

Let W is WHITE, R is RED, B is BLUE
So for n=1:
f(n)=2
W or R;
for n=2:
f(n)=2 too
WR or RW;
And now the most interesting:
for n=3:
f(n)=
We add to combinations of n-1 W or R:  WRW or RWR;
+
We add to combinations of n-2 RB or WB: RBW or WBR;
=f(n-1)+f(n-2);
So you can check it for n=4 and n=5///It's really easy

    #include <stdio.h>
    #include <math.h>
    #define N 100000
    int main(){
        double n;
        double line[N];
        int i = 0 ;

        while(scanf("%lf",&n) != EOF)
        {
            line[i++] = n;
        }
        while(i-- > 1)
        {
            printf("%0.4lf\n",sqrt(line[i]));
        }
        printf("%0.4lf",sqrt(line[i]));
        return 0;
    }

I tried all tests given from kind people in forum and also I tried my own different tests. I have passed in all of it, but I got Wrong Anser 3. Can anybody help me with some tests or someting else?... Please be kind (((

Use properties of arithmetic progression

var
A:array[1..4000] of integer;
B:array[1..4000] of integer;
C:array[1..4000] of integer;
q,w,e,r,t,y,i,o,p,s:integer;
begin
read(q);
for r:=1 to q do read(A[r]);
read(w);
for t:=1 to w do read(B[t]);
read(e);
for y:=1 to e do read(C[y]);
for i:=1 to q do begin
for o:=1 to w do
for p:=1 to e do
if (A[i]=B[o]) and (A[i]=C[p]) then inc(s);
end;
write(s);
end.

I used binary operations to solve the problem and I didn't manage make my algorithm faster. My algorithm is too slow (0.015 sec). Could you give me a little advice how I can optimise my algorithm?

My facebook: https://www.facebook.com/dmitriy.demenev.7

program en;
var a,b,c:byte;
BEGIN
read(a,b,c);
write(b*c*2*5);
END.

Where my mistake? Test 2 - Wrong Answer...
