interviewer, bad body language, drift without their own views, too stiff, lying, too loud to be a good listener, and so on.Tip: The interviewer is not looking for technology stars, but actually has the right technical skills, soft skills, a correct attitude and to gain benefits for the enterprise, comprehensive professional talent. Therefore, it may be useful to study the organization you want to apply for, and learn more about its work practices to adjust the direction and focus of answering q

CF #52 C Circular RMQ (segment tree Interval Update) Description You are given circular arrayA0 ,?A1 ,?...,?AN? -? 1. There are two types of operations with it: Inc( Lf,? Rg,? V)-This operation increases each element on the segment [ Lf,? Rg] (Inclusively) V; Rmq( Lf,? Rg)-This operation returns minimal value on the segment [ Lf,? Rg] (Inclusively ). Assume segments to be circular, so ifN? =? 5 andLf? =? 3 ,?Rg? =? 1, it means the index sequence: 3 ,?

... Exception handling methods. Its violent jumps break the structure of the C language (sequential execution, select execution, loop execution). The classic exception handling in C language causes the logic in the program to mix with a lot of code that handles the exception. The combination of normal logic code and exception handling code causes the code to expand rapidly and is difficult to maintain. In C + + There will definitely be a better way to handle exceptions, and we'll continue to le
