  include<stdio.h>

  int main() { int n ;scanf("%d",&n); int a[n] ; for(int i=0;i<n;i++) scanf("%d",a+i); int cnt =0;

  for( int i=0;i<n;i++) {

  if(a[i] ==1 ) ++cnt; else { // else if( cnt>0) { printf("%d",cnt) ,cnt=0;} if( cnt >0) printf("%d",cnt); cnt =0; } if( cnt >0)
  // cap nhap cho a[n-1] { printf("%d",cnt);

  } int d=0 ;

  include <iostream>

  include <vector>

  using namespace std;

  int main()

  {

  int n; cin>>n;
  
  int a[n],count;
  
  vector <int> v1,v0;
  
  for(int &x : a )cin>>x;
  
  for( int i =0 ; i&lt;n ;){
  
    if(a[i]==0){
  
      count=0;
  
      count++;
  
      while(a[++i]==0)count++;
  
      v0.push_back(count);
  
    }

  2 vòng for là xong, chứ dùng vector lưu lmj cho rối lên. 2 vòng for thì chắc 10^9 vẫn chịu đc
