Problems solving

Question

hi, i want to learn about problem solving in
c++ a guy recommended that i should learn
"algorithms and data structures"
is there any app or a website that could teach me about that and about problems solving
and give me an exam at the end of every tutorial, (just like sololearn) please help

Answer 1

This could be a good starting point:
https://www.tutorialspoint.com/data_structures_algorithms/

Answer 2

probably not the answer you seek but well.

I would recommend to go to a challenge site like projecteuler.com
there you will get ton of problems you can try to solve. the first ones are there so you can learn the limits of integer range of your language and the limits of brute force. Most of the problems need a clever approach.

To direct your interest onto specific problems is a better approach than to "just study algorithms".

The basic algorithms (sorting, packing, graph traversal, minimum paths...) are explained nearly everywhere. there are android apps which even visualize some algorithms. just look into your app store and type "algorithm".
