Hello friend, I have posted the editorial for the contest PRAYATNA which was conducted at Hackerearth yesterday. As i was able to solve only two problems during the contest, I kindly request people who have solved other problems ( except 1st and 2nd ) to share their logic either in the comments below / send a personal message to me either through codeforces or through my blog so that i can update it. Thank you guys!! Link : http://saraguru.weebly.com/how-i-solved

Hello Friends, I have decided to write editorial for few problems regularly so that it could benefit at least few of the beginners to competitive programming. As a beginning i have written editorial for two questions: one problem is from Hackerrank's "zenhacks" contest — Find maximum index product and the other problem is from Timus online judge. I have posted them in my blog (link can be found below). I would like to know how far it is good and hence i request you people to have a look at it and give me some feedback ( both positives and negatives are welcome ).
