A graduate position.

First stage of the process.

An hour and a half with two engineers. They explained the role, asked about experience, and posed two questions.

• The first required a solution using pseudocode.
• The second asked to describe the algorithm for the solution.

Return the number of trailing zeroes in the product of numbers 1-N.

Describe a limited space data structure that will receive unordered inputs and output ordered output (input and outputs are numbers counted from 1 on), and follows certain constraints.
