代码实现：

#include<iostream>
#include<stdio.h>
#include<vector>
using namespace std;
char str[200001];
vector<char>Q[200001];//定义200001个容器
int main()
{
    int i,j,r,flag;
    while(scanf("%s",str)!=EOF)
    {
        r=0;flag=0;
        for(i=0;i<200001;i++)
            Q[i].clear();//容器的清空
        for(i=0;str[i]!='\0';i++)
        {
           if(str[i]=='[')
           {
              r++;
              flag=r;
           }
           else if(str[i]==']')
              flag=0;
           else
           {
               Q[flag].push_back(str[i]);//进入容器
           }
        }
        for(i=r;i>=0;i--)
        {
            for(j=0;j<Q[i].size();j++)
                printf("%c",Q[i][j]);
        }
        printf("\n");
    }
    return 0;
