Hi All..
It’s time to blog again.. Now i will post some small-writeup about the problems were used at this contest..
Well.., about today small-writeup, i will not post my source code anymore. Because
in practice we are sure that reading the source code at first sight will make us
bored and no creativity to implement our own solution..
Okay then, i will only put my ideas in this writeup. So, enjoy it..
