WebTail recursion is another form of recursion, where the function calls itself at the end. Using the tail recursion, we do not keep the track of the previous state or value. Remember the working of a normal recursive function, where we had to go back to the previous calls and add the values till we reached the first call. Here we do not need to ... WebRecursion. When we repeat a similar process many times, it is known as Recursion. In Recursion, a function calls itself many times till it hits some base case, making a recursive tree where we pass every child's output is to its parent.
