Divide 101 coins into three heaps, 50 for the two, and the other 1. 50 heap items, if the weight is equal.It indicates that the counterfeit currency is the sameTake a real coin and compare it with the counterfeit coin to determine which coin is heavier. If the weight is not equal, it means that the remaining coin is true, and then there is a false one in the two piles of 50, and the balance is not balanced.Using a real coin is obviously different from the two.Another idea is that if there is

C ++ heavy-load operations, type conversion, and heavy-load operations 1. Basic Concept 1.1 Basic Points 1.2 call method of overloaded Operator Functions 1) Non-member functions call operator + as the non-member functions of the object data1 and data2 Data1 + data2; ==> operator + (data1, data2 ); 2) call operator + as a member function of the object data1 Data1 + data2 ==> data1.operator +

Approximate test instructions:In order to protect the grazing environment and avoid excessive biting of the turf in the same place, ranchers decided to use the continuous migration of livestock to feed the way to protect the pasture. However, livestock will also gnaw on the forage on the road during the migration, so if the same road is used for each migration, the road will be damaged by biting too much.The ranchers now have an F farm, which is known to have at least one path connected (not nec

In the interview, we often go to the array for weight. As a qualified front-end developer, it is not known that several ways to go heavy are not in the should. Not much nonsense to say directly open the ... One, IndexOf () method Implementation idea: Use the indexof () method to determine if there is a value in the new array, and if not, push the value into the array The code is as follows Copy Code

C ++ implements heavy-load ostream and heavy-load ostream #include The main note is to define the function as a friend function of the class Point outside the class. In addition, pay attention to the return OS to achieve the chain function. Heavy Load of C ++ into ostream class Ostream has a char * overload,Const char * and const void *. Other pointers are output

Heavy Load ++ and --, heavy load -- Unlike the common binary operator "+/-", the auto-incrementing and auto-subtraction operator "+ +/--" requires extra attention to distinguish between front-end and back-end. The current processing method is: (as a member function) the front "++" does not accept any parameters, while the rear "++" accepts an int type parameter, although it is useless, it helps the compiler
