i don't understand why RTE i used array size larger than 1000000 :


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



int main()
{
char ch[1000010];
long int i,j[1000010],k[1000010],n,carry,m;

scanf("%ld",&n);

for(;n>0;n--){

scanf("%ld",&m);
for(i=0;i<=m;i++) ch ='0';
carry=0;
for(i=0;i<m;i ...

i used long double n dividebygcd but why WA:



#include<stdio.h>
#include<math.h>

long double gcd(long double a,long double b)
{
if(fmod(a,b)==0) return b; else return gcd(b,fmod(a,b));
}


int main()
{

long double g,i,j,k,n,mul,div;
double up,down;
scanf("%Lf %Lf",&n,&k);
while(n!=0 ...

ya thanx- i got AC

i think my code outputs correctly . but why WA? any1 pls help me?

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


int main()
{
int i,j,k,n,m=0,t1[102],t2[102], max;
char time1[102][6],time2[102][6],app[256];
while(scanf("%d",&n)!=EOF){ max=0;
for(i=1;i<=n;i++) {scanf("%s %s",time1 ,time2 );gets(app ...

the difference is only 4 the imput "64 1" . i changed my code this way n it gives same output as u. so why WA.
#include<stdio.h>
#include<math.h>

int main()
{
long n,m,i,j,kk,kkk,p;
double k,l;

while(scanf("%ld %ld",&n,&m)!=EOF){p=1;
if(n==1 || m==1 || n==0 || m==0) {printf("Boring\n ...

i made more than 20 submissions 4 this pob. i dont find the mistake why it gets WA.any1 pls help me:

#include<stdio.h>
#include<math.h>

int main()
{
long n,m,i,j,kk,kkk,p;
double k,l;

while(scanf("%ld %ld",&n,&m)!=EOF){p=1;
if(n==1) {printf("Boring\n");continue;}
else if(m==0 || n==0 ...

i think i outputted correctly.so why WA:

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



int main(void)
{

char str[100][61],temp[61];
int c,r,i,j,k,n,s,t,ma,len[100],max;

while(scanf("%d",&n) !=EOF){max=0;
for(i=0;i<n;i++) {scanf("%s",str );
if(max<strlen(str )) max=strlen(str );}

for(i=0;i<n ...

i had been stack in this prob. 4 many days.can any1 pls help me.
what's wrong:
#include<stdio.h>
#include<string.h>



int main(void)
{

char str[100][61],temp[61];
int c,r,i,j,k,n,s,t,len[100],max;

while(scanf("%d",&n) !=EOF){max=0;
for(i=0;i<n;i++) {scanf("%s",str );
if(max<strlen(str ...

can any1 pls help me abt 424-integer inquiry my code below :
#include<stdio.h>
#include<string.h>
int main(void)
{

char p[101][101],q[101][101],res[101];
int i,j,t,max,len[100],sum=0,c=0,k=0;

for(i=0;;i++) {scanf("%s",&p );if(strcmp(p ,"0\0")==0) break; }
max=i;
for(i=0;i<max;i++) len ...

i dont understantd why my code outputs somethin strange for inputin 1st samp in. for 1st time. but when 2nd time i input somethin it outputs correctly. some 1 pls explain me whats wrong ?

#include<stdio.h>

int main(void)
{

char a[200],str[200],max;
int i,j,k;

while(gets(str)!=NULL){
max=0 ...

can anyone pls explain me some things:

1. what does it mean by "input may be with end of file"?
2. what does gets(gets(str)) means?
3.what's wrong with my code :

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

int main(void)
{

char str[1000000],ch;
long int i,j,c,flag,temp,count=0,p,q;
gets(str ...

i dont understand why CE with this simple sortin code.anyone pls help.
#include<stdio.h>
#include<conio.h>
int main()
{

int i,j,count,temp,c;
unsigned long a[1000];

while(scanf("%d",&c)!=EOF){
count=0;

for(i=0;i<c;i++) scanf("%lu",&a );

for(i=0;i<c;i++){
for(j=i+1;j<c;j++){
if(a >a[j]){
temp ...

yeah!!thanx i got AC

i dont understand why i got TLE all the time when dealin with prime numbers.pls anyone tell me whats wrong with my code for 10200 :
#include <stdio.h>
#include <math.h>


int isprime(long num);

int main()

{

int a,b,i,prime,tot;
long res,j,n;
double per,t,p;

while(scanf("%d %d",&a,&b)!=EOF ...
