“TESTCASE_1”: “7\n64 34 25 12 22 11 90\n###—###SEPERATOR—###—\n12 22 11 25 34 64 90 \nSorted array:11 12 22 25 34 64 90”, “TESTCASE_2”: “9\n64 34 25 12 22 11 90 35 26\n###—###SEPERATOR—###—\n12 22 11 25 34 26 35 64 90 \nSorted array:11 12 22 25 26 34 35 64 90”, “TESTCASE_3”: “8\n14 83 25 47 9 77 1 0\n###—###SEPERATOR—###—\n14 9 25 1 0 47 77 83 \nSorted array:0 1 9 14 25 47 77 83”, “TESTCASE_4”: “0\n###—###SEPERATOR—###—\n0”, “TESTCASE_5”: “0\n###—###SEPERATOR—###—\n0

ANSWER

#include <iostream>
using namespace std;
int main()
{int n,arr[100];
 cin>>n;
 for(int i=0;i<n;i++)
   cin>>arr[i];
 for(int i=0;i<n-1;i++)
 {for(int j=0;j<n-i-1;j++)
  {if(arr[j]>arr[j+1])
   {int emp=arr[j];
    arr[j]=arr[j+1];
    arr[j+1]=emp;
   }
  }
  if(i==2)
  {for(int k=0;k<n;k++)
     cout<<arr[k]<<' ';
  }
  
 }
 cout<<"\nSorted array:";
 for(int k=0;k<n;k++)
   cout<<arr[k]<<' ';
 

	return 0;
}
