Recursive function for calculating
n! implemented in Python:
Behind the scenes, each recursive call adds a stack frame (containing its execution context) to the call stack until we reach the base case. Then, the stack begins to unwind as each call returns its results:
A demonstration should make things clearer. Let’s calculate
1 + 2 + 3 ⋅⋅⋅⋅ + 10 using recursion. The state that we have to maintain is (current number we are adding, accumulated sum till now) .
Serverless functions save developers a ton of trouble managing the backend infrastructure. It also simplifies the development process as developers only need to focus on the business logic. This article is a step-by-step guide on how to write and deploy your own WebAssembly serverless functions on AWS Lambda, Amazon’s serverless computing platform. In our demo, WebAssembly functions are executed with the WasmEdge runtime. The figure below shows the overall architecture of our solution.
Phone interviews are efficient time savers for both the candidate and the employer.
Initially considered a screening round for the benefit of the employer, a phone interview also helps the candidate weed out any potential deal-breakers before investing time, money, energy and resources to give a personal face-to-face interview (wherever that is happening).
