need algorith to combine sets

Hi I have to lists, using C# and the look like
List <stringreportna me = new List<string>();
List <Int32 reportnumber = new List <Int32>();
They get filled with corresponding data, both lists are the same size. I
need to create a third string lists and fourth integer list that combines the
report names when the report numbers are the same. For example the data
might look like
reportname report number
vehicles 1
bikes 1
cities 2

so I would like to create a third and fourth list that would have
report name report number
vehicles, bikes 1
cities 2
thanks.

Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers. The idea...
