I’m working on solving the 3Sum problem, where I need to find all unique triplets in an array that sum up to zero. I’m currently using an unordered_map to store elements and then check for triplets. However, I need help with efficiently removing duplicate triplets from my results.

I am implementing an LRU cache for a problem where I need to store key value pairs.

I am using mymap.find(key)==mymap.end to see if key is present in my map or not.

I am currently writing a console program in C++ that builds a network/graph of nodes and arcs that connect to eachother using unordered maps. The purpose of the application is to demonstrate the “most efficient” way of processing commands and retrieving information from the network/graph. I’ve attached [a diagram of a similar example].(https://i.sstatic.net/51FY0RHO.png).

I have an issue with unordered_map.
I cannot modify the definition of unordered_map as it’s defined like that in memory and I want to read it from there to it.
