Ans. Brute Force Approach
We need to keep exploring the given string from current position ‘i’ to until we wouldn’t find a position such that substring ‘i’ to ‘j’ exists in the dictionary.
The algorithm looks like:
1. Store all words of the dictionary in unordered_map to speed up checking whether a current word exists in the dictionary or not?
2. If sentence size is ended then just return with a null string of list.
3. Else,
   1. You start exp...read more

Ans. 
We can keep track of the level of a node by passing a parameter to all recursive calls. The idea is to keep track of the maximum level also. Whenever we see a node whose level is more than the maximum level so far. We print the node because this is the first node in its level (Note that we traverse the left subtree before the right subtree).
