Thanks a lot Master

hey guys
how about this trick it may help

hey guys i wounder about the online judge verdicts how does the judge do judge the submitted codes ? it gives RE if the program crashes during the test cases but i mean in general and especially for the TL does it mean that your code is right but not efficient or maybe it's wrong that means the judg...

hey guys i spent a whole day solving this problem and finally got it right and want to revenge :evil: it's not really that hard but it's kind of a mystery for you who gave up here's my incompetence approach if you wish for it's very simple by the way hope to be useful #define _CRT_SECURE_NO_WARNINGS...
