# ZIO 2011 Question Help

Hello @sumit_king ,

Can you tell your approach for the problem ? ( will be easy to understand what you are doing wrong )

I am going on each number and then counting the numbers which are smaller than the number which is fixed and each number which i am selecting is bigger or equal to the previous number…

Did you got that @sudheerays123??

Btw @sudheerays123,

i have got the answer for next two parts by this method…But the answer for the 1st part is going wrong…

Yes I think this is correct

Send me your solution i.e for all the buildings , write the number of buildings you can connect from that building

Then , i can tell you where you are wrong !

The Sequence is as follows :

5+1+1+2+1+4+5+1+1+5+2+1+1+2+1+1+3+1+1+0 = 39

Is this correct @sudheerays123 ??

This is 3 not 5

The number of connections for building 7 is 3 not 5 , check once again , you might have done some mistake

Now you will get 37 as your answer !

Thats it !!
