A solution to last week’s challenge can be found here.
On daily basis, call centers are handling customers requests using a chat feature. In parallel, their analysts are checking data to report on their operators performance.
A data analyst in a major call center was responsible to report on their numbers by the end of the day. He wants to convert the time format from "HH:MM:SS" to "Hours Minutes Seconds", and his boss does not want any unnecessary information in the output. So meaning, no leading zeros and attribute should be removed if it is zero.
Using the data sets provided create an output with the format that the data analyst needs.
There are a pile of ways of doing this. I think I can see what Qiu was looking for based on the format of the solution and his including a mapping table for the time units, so I tried to follow that.
