CodeChef JULY long and cookoff problems

My performance was bad in July. Could solve 2 problems in the long contest:CSUB, RETPO and 2 in the Cookoff: RRCOPY, RRSUM.

Got stuck with FROGV in the long contest and FRNDS in the Cookoff. Need to do better.

Read Anudeep's blog to get more inspiration:

Neat introduction to Combinatorial games

I was looking to solve Hackerrank w7 challenges and one problem was about the game of Nim. After that, I started to look up good introductions to Nim. I found this one interesting: comb.pdf
I found it very useful to understand the game.

This one talks about Backward induction, P-positions and N-positions. Just what is required.

Udacity.com : CS101: Introduction to Computer Science done :-)

Got my CS101 completion certificate. Awesome learning and Prof.David Evans rocked the students for sure. 

Next will be start off my project (more later). 

Also, started the CS212: Design of Computer Programs by Dr.Peter Norvig.

Sad part is that Udacity is discontinuing the issue of certificates for the free courses :-(

CodeChef May 2014 Long challenge problems...

I have always regarded CodeChef very highly for the kind of problems they come up with and the tutorials after the contests. May 2014 has quite a few interesting problems of which I have solved 3: OJUMPS, RRSTONE and COMPILER. Attempting the Strange Matrix now (CHEFBM)

The name in CAPS are the problem codes.
Feels blissful to solve problems :-)

Book: Elements of Programming Interviews

Elements of Programming Interviews (EPI) is an an amazing book. Here's the official link for the book. I tried solving one of the very first problems about maximizing the profit of buying and selling shares. A very interesting problem indeed. Strongly recommend this book for people interested to sharpen their algorithm skills.
I also have their previous version: AFI (Algorithms For Interviews).
A big thank you to the authors for a superb book.

Book: How to solve it by Prof.George Polya

Bought the book 'How to solve it' by Prof.George Polya. Need to internalize the methods. Highly recommended for problem solvers :-)
