Hi guys,
Is recursion the efficient way of solving the questions (if we look only at the time complexity)??

That depends entirely on what problem you're dealing with. Using (naive) recursion to calculate Fibonacci numbers is a very bad idea, for example. But for traversing a tree, recursion is quite good.
Recursion helps to break down a problem, but it isn't always good at reusing intermediary results, which means you can end up doing the same work many times over.

Recursion is a technique in which a function calls itself again and again until the lower limit is reached to perform a repeated task.
