### Re: 11063 - B2-Sequence

I found a couple of mistakes...

First, the sequence must start with the number greater than 0.

Second,

First, the sequence must start with the number greater than 0.

Second,

if(i>=2)if(Arr==(Arr[i-1]+Arr[i-2]))flg=1;

this line is wrong.

Consider the test case:

3

1 3 4

The sequence is a B2 sequence but your output shows it is not a B2 sequence.this line is wrong.

Consider the test case:

3

1 3 4

The sequence is a B2 sequence but your output shows it is not a B2 sequence.

### Re: WA 414 pls help

you should keep on bringing the two surfaces closer as long as there is atleast 1 gap in each line.....when this can no longer be done count the remaining gaps in all the lines. Hope this helps.

### Re: 10041 - Vito's Family

your logic is wrong.....

consider the test case:

4 1 2 4 5

the answer is 6( vito should build his house in 3 ) but your output is 4.

what should have been the idea for solving this problem??oops, this is not the intended way to solve this problem. The test cases are not strong enough but I admit that I have no idea how to generate good ones. Any one has some ideas?
