[luffymine]

m getting wa . saw other posts on bureau as well and code seems to be working fine but obviously something is wrong, Please someone point out where the code fails..

#include<cstdio>
#include<string.h>
#include<stdlib.h>
#include<iostream>
using namespace std;
int main()
{
	char s[100];
	long int k,cases,testcases,cancel[100005],ans[100005],i,j,flagd,count;
	scanf("%ld",&testcases);
	while(testcases--)
	{
		flagd=0;
		scanf("%ld",&cases);
		i=1;
		count=0;
	//	memset(cancel,0,sizeof(long int)*100005);
		for(k=1;k<=100003;k++)
			cancel[k]=0;
    	
	while(i<=cases)
	{
		scanf("%s",s);
		if(s[0]=='d')
		{
			flagd=i;
			count=0;
		}
		else
		{
			scanf("%ld",&j);
			if(flagd>0)
			{
				cancel[j]=i;
				if(cancel[j]<flagd)
				{
					count++;
				}
			}
		}
		i++;
	}
	count=0;
//		printf("%ld\n",cases-count);
		for(i=1;i<=cases;i++)
		{
			if(cancel[i] < flagd)
			{
				count++;
				ans[count]=i;
		//		printf("%ld ",i);
			}
	//			cancel[i]=0;
		}
		printf("%ld\n",count);
		for(i=1;i<count;i++)
		{
			printf("%ld ",ans[i]);
		}
		printf("%ld\n",ans[count]);
	}
	return 0;
}
