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…

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 !!

Oh yes!! I got that …
Thank You So Much!!@sudheerays123
