You have been given two integer arrays/list(ARR1 and ARR2) of size N and M, respectively. You need to print their intersection; An intersection for this problem can be defined when both the arrays/lists contain a particular value or to put it in other words, when there is a common value that exists in both the arrays/lists.

Note :

Input arrays/lists can contain duplicate elements.

The intersection elements printed would be in the order they appear in the first array/list(ARR1)

You are given an array of integers ‘A’ having ‘N’ number of elements. It is given that all the numbers in the array occur twice except the two numbers that appear only one time. You need to find those two non-repeating numbers.

For Example:

If the given array is [ 4, 7, 3, 2, 7, 2 ], you have to find ‘4’ and ‘3’ as 4 and 3 occur one time, and the rest of the elements ( 7 and 2 ) are occurring twice.

Given an integer ‘N’ representing the number of pairs of parentheses, Find all the possible combinations of balanced parentheses with the given number of pairs of parentheses.

Note :

Conditions for valid parentheses:
1. All open brackets must be closed by the closing brackets.

2. Open brackets must be closed in the correct order.

For Example :

()()()() is a valid parentheses.
)()()( is not a valid parentheses.
