Jan 1st 2014 (It's a New Year)

Place - Bangalore

Learn number theory. Got many interesting resources to learn advanced data structures including heavy light decomposition. Today's plan is to implement maxflow algorithm and solve at-least one problem.

Maxflow is one cool concept and it's application are many.
Today I need solve at-least one srm and I haven solved the srm 300 div21000 pts.
Starting my day with srm 300 div21000 pts.

Cool blog http://praveendhinwacoding.blogspot.in/2013/06/700-problems-to-understand-you-complete.html
Consist of complete reference to learn segment tree, BIT, and also dp.
Need to solve 3-4 dp problem today. Brush up old concept and implement it.
My new-year resolution start using git-up and upload the implemented algorithm :).
Wishing everyone in the world a happy new-year.

Many of us know have to traverse array in anticlockwise manner but I wanted to share this neat code, come in handy for many cases.
Let n denote number of element in the array. startedpos denotes the starting index of the number.

for(int i=(startedpos+n-1)%n ; i!=startedpos; i=(i+n-1)%n);
