You are given an integer N. Your task is to return a 2-D ArrayList containing the pascal’s triangle till the row N.

A Pascal's triangle is a triangular array constructed by summing adjacent elements in preceding rows. Pascal's triangle contains the values of the binomial coefficient. For example in the figure below.

For example, given integer N= 4 then you have to print.

1  
1 1 
1 2 1 
1 3 3 1

Here for the third row, you will see that the second element is the summation of the above two-row elements i.e. 2=1+1, and similarly for row three 3 = 1+2 and 3 = 1+2.

Ninja is trying to write a function that takes two integers and returns their sum. But, due to some faults in his keyboard, he can not use the “+”, operator, which means he is not able to simply return ‘A’ + ‘B’, where ‘A’ and 'B' are the numbers to be added. You need to help Ninja in finding the sum of two numbers without using the "+" operator anywhere in your code.

Note:

 You should also not use the increment "++" operator too.

For example :

You are given A = 4, B = 6, their sum = 10, you need to return 10.

You have been given an input integer 'N'. Your task is to print the following binary pattern for it.

Example

Pattern for 'N' = 4

1111
000
11
0

The first line contains 'N' 1s. The next line contains 'N' - 1 0s. Then the next line contains 'N' - 2 1s and so on.
