Objective: - Given a binary tree and X, Print all the paths starting from root so that sum of all the nodes in path equals to a given number.
- Create a global variable as String = path.
- Do the preorder
- if root is greater than Sum required, return.
- If not then, add root to the path and update the required sum (sum=sum-root.data).
- if sum required =0, means we have found the path, print it.
- See the code for better understanding.
