I think you should rewrite the cmp function because you can write it simply. Otherwise I have to go through the whole function, but I am lazy :D. If you cant find the any simple cmp function then PM me.

};

int sort(const void *aa, const void *bb)
{
	T *p = (T *)aa;
	T *q = (T *)bb;

	if( p->b == q->b)
	{
		if(p->a%2==0 && q->a%2==0)
		{	
			if(p->a > q->a)
			{
				temp=p->a;
				p->a=q->a;
				q->a=temp;
				return -1;
			}
			else
				return -1;
		}
		else if(p->a%2!=0 && q->a%2!=0)
		{
			if(p->a < q->a)
			{
				temp=p->a;
				p->a=q->a;
				q->a=temp;
				return -1;
			}
			else
				return -1;
		}

	T s[10001];
int main()
{
 

	while(scanf("%lld%lld",&n,&m)==2)
	{

		{
			printf("%lld %lld\n",n,m);
			break;
		}
		
		for(i=0;i<n;i++)
		{
			scanf("%lld",&s[i].a);
			s[i].b=s[i].a%m;
		}

		qsort(s,n,sizeof(T),sort);

		printf("%lld %lld\n",n,m);
		for(i=0;i<n;i++)

}

long cmp(long *a,long *b)
{
	long rm,rm2;
    long od,ev;
	long *x=(long *)a;
	long *y=(long *)b;
    rm=*a%m;
    rm2=*b%m;
    od=abs(mod(*a,2));
    ev=abs(mod(*b,2));
    if(rm<rm2)
		return -1;
	else if(rm>rm2)
		return 1;
    else

        for(i=0;i<n;i++)
			scanf("%ld",&data[i]);
		printf("%ld %ld\n",n,m);
        qsort(data,n,sizeof(long),(int (*) (const void *,const void *))cmp);
        for(i=0;i<n;i++)

Hello friends. Finally got the AC. For those who are getting WA, check if you have used something like this:

int upcomp(const void *a, const void *b){
return (*(int *)a) - (*(int*)b);
}

This will cause overflow can gives wrong output! I have been using this for quite a long time though :-? . Use ">" and "<" to compare instead of this.

finally, i got AC...
i just use

Code: Select all

bool cmp(data a, data b)
{
    if (a.mod==b.mod)
        if (a.stat==b.stat)
            if (a.stat==1)
                return a.angka > b.angka;
            else
                return a.angka < b.angka;
        return a.stat < b.stat;
    return a.mod < b.mod;
}
and

Code: Select all

sort(v.begin(),v.end(),cmp);

Please Any body help me.
I got a couple of Wrong Answer. My code pass all the test found in this thread

Code: Select all

#include<iostream>
#include<cstdio>

#include<algorithm>

using namespace std;

long int m;

bool cmp(long int a,long int b)
{
long int ra,rb,p,q;
if(a<0) 
 p=(-1)*a;
else 
 p=a;

if(b<0) 
 q=(-1)*b;
else 
 q=b;

ra=a%m;
rb=b%m;

if(ra==rb)
  {
   if(p%2 ==0 && q%2==0)
    return (a<b);
  else if(p%2==1 && q%2==1)
    return (a>b);
  else if(p%2==1 && q%2==0)
    return true;
  else if(p%2==0 && q%2==1)
    return false;
  }    
else if(ra>rb)
    return false;
else    
return true;

}

int main()
{

long int i,a,n;
vector<long int> aa;
//freopen("a.txt","r",stdin);
//freopen("b.txt","w",stdout);

while(scanf("%ld %ld",&n,&m)==2)
{
pf("%ld %ld\n",n,m);

if(n==0 && m==0) break;

aa.clear();

rep(i,n)
{
sf("%ld",&a);
aa.pb(a);
}

sort(all(aa),cmp);

rep(i,n)
pf("%ld\n",aa[i]);

}    
re 0;    
}

I also got many RTE's before finding the mistake.

if(abs(a)%2==1 && abs(b)%2==1) //correct,ac

if(a%2=1 && b%2==1) //RTE

Hope this helps :).
