# Algorithm Practice: Product Sum

Happy 2021! It’s a new year and a fresh start, and we’re diving right back in to mastering algorithms.

I have been busy preparing for upcoming interviews and doubling down on getting algorithm practice in, so this week, let’s get in to the third iteration of the Algorithm Practice series.

### Product Sum

This week, we will do a walkthrough of the Product Sum algorithm problem. It is another algorithm that often comes up during technical interviews. Given an array, our task is to write a function that returns its product sum.

Some things to clarify before we get in to thinking about how to tackle the task at hand. The given array (what we’ll call a “special” array) is always a non-empty array containing integers or other nested “special” arrays.

And what do we mean by product sum? The product sum of a “special” array is the sum of its elements, but with a catch — where there are nested “special” arrays, the elements of the nested array is summed up and multiplied by their depth level (how nested the “special” array is).

## An Overview of our PH Launch for AskMakers v2.0

Oh…I am so sleepy…because I launched AskMakers 2.0 on Product Hunt and I have been monitoring it almost without sleeping😪

The first version of it was launched about 10 months ago.

I worked so hard on it and it got over 100 upvotes within 24 hours for the first time🤩To make an app useful, I sent emails to ask successful makers to join AskMakers.

I am nobody, just a software developer from Tokyo (currently in Vancouver), however, some of them signed up on and support it!! Unbelievable🤯

Thank you JustinHariAmieJonathan, and Jaime😆

After that, it took 10 months until the launch of 2.0…

I always thought like I need to add more features to launch, and I felt like I can never launch it…I should not try to be perfect.
