Facebook hacker cup question D1

What was the mistake?

i was redeclaring the array inside main() too.

use online compiler , i use “compile c++ gcc online” , if the array is so large.

//g++  7.4.0

#include <iostream>

int main()
{
    int n=100000;
    while(n--){
        int a[100000000]={0};
    }
}

I used a single vector of size 1e6 + 5. It was ok with my system. and also on Online platforms, make sure you not running out of stack due to other reason.

finished but printing nothing
,this is working fine
