Chintu has a long binary string ‘str’. A binary string is a string that contains only 0 and 1. He considers a string ‘beautiful’ if and only if the number of 0's and 1's in the string are equal.

For example :

0011 , 1100 , 101010 etc are beautiful strings whereas 1110, 0001,10101 etc are not beautiful strings.

Now Chintu wants to split the string into substrings such that each substring is beautiful. Can you help Chintu to find the maximum number of beautiful strings he can split the string into? If it is not possible to split the string in such a way that all strings are beautiful, return -1.

For example :

Let the given string be “101001”
We will return 3 as we can divide the string into 3 beautiful strings “10” “10” and “01’.

Given 'N' number of intervals, where each interval contains two integers denoting the boundaries of the interval. The task is to merge all the overlapping intervals and return the list of merged intervals sorted in ascending order.

Two intervals will be considered to be overlapping if the starting integer of one interval is less than or equal to the finishing integer of another interval, and greater than or equal to the starting integer of that interval.

Example:

for the given 5 intervals - [1,4], [3,5], [6,8], [10,12], [8,9].
Since intervals [1,4] and [3,5] overlap with each other, we will merge them into a single interval as [1,5].

Similarly [6,8] and [8,9] overlaps, we merge them into [6,9].

Interval [10,12] does not overlap with any interval.

Final List after merging overlapping intervals: [1,5], [6,9], [10,12]

You have been given a Binary Tree of 'n' nodes, where the nodes have integer values

Print the left view of the binary tree.

Example :

If the input tree is as depicted in the picture: 

The Left View of the tree will be:  2 35 2
