#include<stdio.h>

int main(){
  
  int N, i, j , m, tes = 0;
  scanf("%d",&N);
  
  long A[N];
  
  for(i = 0; i < N; i++){
    A[i] = 0;
  }
  
  for(i = 0; i < N; i++){
    scanf("%d", &m);    
    
    for(j = 0; j < N; j++){
      if(A[j] == m){
        A[j] = 0;
        tes++;
      }
      
    }
    if(tes == 0){
      for(j = 0; j < N; j++){
        if(A[j] == 0){
          A[j] = m;
          break;
        }
      }
    }
    tes = 0;
    
  }
  for(i = 0; i < N; i++){
    if(A[i] != 0){
      tes++;
    }
  }
  
  printf("%d\n", N);
