Here's my code:

C:

#include<stdio.h>
#include<string.h>
char sieve[19999580];
long count=0,twin[100005],i,j;
void main(){
memset(sieve,1,sizeof(sieve));
for(i=4,j=6;i<=19999558||j<=19999558;i+=2,j+=3) sieve[j]=sieve =0;
for(i=5;i<=19999558;i+=2){
if(sieve &&sieve[i-2]) twin[count++]=i-2;
for ...

I don't understand why WA.

Here's my code:

#include<stdio.h>
#include<string.h>

int count,n,len;
char num[200],string[300],s[300];

void permute(){
int i;

/*Uppercase letters*/

for(i=65;i<91;i++){
if(num ){
string[count++]=i;
num --;
if(count==len) printf("%s\n",string);
else permute ...

[cpp]
#include<stdio.h>
#include<malloc.h>

struct person{
int n;
struct person*next;
}*head,*tail,*cur;

void build(int p){
head=tail=cur=0;
for(int i=0;i<p;i++){
cur=(struct person*)malloc(sizeof(struct person));
cur->n=i+1;
if(!head) head=cur;
else tail->next=cur;
tail=cur;
tail->next ...

Could anybody help me??
I got WA all the time.

Here's my code:
[c]
????????????????
[/c]

Never mind!!

Mine gives WA too. Here's my code:

[c]
#include<stdio.h>
#include<string.h>
int i,min,s[30],s1[30];
char a[1002],b[1002];
void main(){
while(scanf("%s %s",&a,&b)==2){
memset(s,0,sizeof(s));
memset(s1,0,sizeof(s1));
for(i=strlen(a)-1;i>=0;i--) s[a -97]++;
for(i=strlen(b)-1;i>=0;i--) s1[b -97 ...

Can anyone help? This problem's driving me nuts!!!
Anyone can give some sample I/O???
Thanx in advance!!

#include<stdio.h>
#include<string.h>
int l,c;
char v1[50],v2[50],t;
void main(){
while(scanf("%s",&v1)!=EOF){
gets(v2);
printf("%s (to%s)\n",v1,v2);
l=strlen(v1)-1;
if(v1[l]=='r'){
if(v1[l-1]=='a'||v1[l-1]=='e'||v1[l-1]=='i') {
t=v1[l-1];v1[l-1]=0;
if(t=='i') c=1;
}
}
if(!v1[l-1 ...

Thanks to both of you.
I got AC now!!
God bless you

Anybody can tell me where my mistake is? This problem REALLY REALLY drives my crazy !!!!!!!!!!!

Here's my code

[c]#include<stdio.h>
int i;
int s,h,u,f,d;
void main(){
while(1){
scanf("%i %i %i %i",&h,&u,&d,&f);
if(h==0){break;}
h*=100;u*=100;d*=100;
for(i=1,s=0,f*=(u/100);;i++){
s+=u;
if(s ...

Got AC now!!!!
But when either of the side is 0, would that be a triangle? It should be a line instead of a triangle!!
But THANK YOU VERY MUCH !!!!!
Have a nice life !!

Off course, that's why I use the code:
[c]while ( scanf ( " %i ", & n ) ! = EOF )[/c]
Oh, wait a minute! Do you mean that the multiple input is not the n value?
In that case, there can be 2 possibilities :
1. One board that is played more than once.
2. Many board, but each board played only once ...

I've tried everything, but still WA

C :
#include<stdio.h>
#include<string.h>
int i,j,k,l,m,n,sum,yes;
char game[15][15],board[15][15];
void main(){
while(scanf("%i",&n)!=EOF){
for(i=0;i<n;i++){scanf("%s",&board );}
for(i=0;i<n;i++){scanf("%s",&game );}
for(i=0;i<n;i++){
for(j=0;j<n;j++){
if ...

I'm aware that this is a multiple input problem. Btw, It's said if a bomb is encountered during the game, ALL POSITION CONTAINING THE BOMB MUST PRINTED '*' AND ALL OTHER POSITION MUST CONTAIN '.'.
Oh, should I print extra blank line between two consecutive outputs?
Thx anyway!!

You mean one of them (a,b,c) or both ((a,b),(b,c),(a,c)) or the three of them are zeroes?
And what if these zeroes occur? should I ignore this input (since it can produce negative result in the sqrt which is undefined) ?

consider this input :
4
. . . *
. * * .
. . . .
* * * *
xxx.
xx..
x...
x...
What will the output be?
Output 1
. . . *
. * * .
. . . .
* * * *
Output 2
123.
1**.
3...
****

Or neither of them?, if so what will it be?
