In Python, we know that afunctioncan call other functions. It is even possible for the function to call itself. These types of construct are termed as recursive functions. The following image shows the working o

A recursive formula relates each term in the sequence to previous terms in the sequence. This is different than an explicit formula, which describes each term in the sequence as a function of its position. Let's look at the Fibonacci sequence. Image source: By Caroline Kulczycky Let's br...
Example 2: Eligible for tail recursion because function call to itself fibonacci(n-1, a+b, a) is the last operation. fun fibonacci(n: Int, a: Long, b: Long): Long { return if (n == 0) b else fibonacci(n-1, a+b, a) } To tell compiler to perform tail recursion in Kotlin...
The recursive function is more readable because it follows the definition of Fibonacci numbers: However, since the stack’s depth is limited, it will throw an overflow for large . In contrast, the iterative function runs in the same frame. Moreover, the recursive function is of exponential tim...
In this manner,factorizewill return a generator, which is basically a view wrapper to the function above which generates consecutive elements on the range "on the fly", while also suspending execution of the function between accesses to the resulting range. This way, we avoid the need to store...
