#include<stdio.h>
#define N_MAX 100000
#define A_MAX 10000

int main(){
	int N,A[A_MAX],i,tmp,j,res,flag;
	scanf("%d",&N);
	for(i=0;i<N;i++){
		scanf("%d",&A[i]);
	}
	for(i=0;i<N;i++){
		flag=0;
		tmp=A[i];
		for(j=0;j<N;j++){
			if(A[j]==tmp)flag++;
		}
	if(flag%2!=0)res++;
	}
	printf("%d\n",res);
}
