WebApproach. The approach is pretty simple. We can check that if at a certain point, the value of a node is what we need, and it is a leaf as well. Then, we can conclude that a path exists from root to this point having target sum. So, it is intuitive that as we recursively jump to any child, we must pass on the remaining sum to complete the target.
