INTRODUCTION TO
PROBLEM-SOLVING
WHAT IS PROBLEM-SOLVING?
EX:
Given a knockout tournament with 16 teams.
How many matches will be played until we can
declare a winner?
EX:
Calculate the sum of integers from one to n.
That is calculate 1+2+3+4+....+n
WHY PROBLEM-SOLVING?
First of All
It is fun!
Develops the way of thinking in
real life (known as smart)
Required skill for Software job
interviews
CV!
Remember not to expect a job
with a problem solver title, But
you will need the skill in many
aspects of the job
General
Roadmap to
Problem-Solving
1-Programming Language
C++ vs Python
Why Python?
Easy (High level language)
Language is not the primary task
If you start with a complex language
you might quit
It's used in A lot of fields. (EX: AI)
Shorter codes when compared with
C++. Hence less time to write the code
Why C++?
It teaches you the basics of
programming in a good way since it's
considered a low-level language.
Faster than python.
you have more control in C++.
You will not need the speed of
C++ in your journey of being a
good problem solver. But you
will need its speed to be an
expert problem solver.
There is no correct answer about
which language is better to learn as
your first programming language. It
depends on your target. Remember
you can always learn both and
decide for yourself.
2-Start solving problems
Codeforces (My number one
recommendation)
Hackerank (needs VPN)
Leet code (based on interviews)
Remember in solving problems it is
important to read tutorials for
problems that you could not solve
and even for the problems that you
solved!
You are not getting better if you can
solve all problems you encounter.
3-Reading
Competitive Programmer’s
Handbook
In the start of the journey try to
solve A lot of problems and learn by
reading their tutorials.
When you feel that most of the
problems you are not solving are
because lack of information start
reading the handbook.
It is always helpful to discuss the
problem with someone that solved
the problem and understand how they
think and how they solved it.
try and get into a community of
problem solvers.
Feel Free to contact me with any problem
you encounter, If I can't discuss the
problem with you at least I will get you
involved in a community that will.
