province. Get all the intersecting objects on the Y axis in a similar way. The simultaneous intersection in two directions indicates that a collision has occurred in the game.Algorithm time complexity theory is n*n, but in fact there is not so high, the general game, the object is relatively sparse, so it is easy to jump out of the inner layer of the loop.When the object is moving, in order to avoid re-doing the projection operation, you can find the binary search in xlinelist directly, then mo

return false; -}Fourth limit: The length of the list is arbitrary, and the loop may appear in any position.Title Analysis: According to the book, with a fast pointer (two steps each) a slow pointer (one step at a time), if two pointers meet, indicating a ring.This theory can be simply proved: if in a moment the slow pointer to the position of the ring, then the fast pointer must have been in the ring for a long time. At this point if the fast pointer and the slow pointer distance of M-step

The original code should be this way, it is strongly recommended to put the variable behind if (a==b)//If a==b, execute the following code {...} However, in the absence of control of their own agile thinking situation, this error causes the program to execute any time the code in the IF statement (a=b) {...} As you know, the IF judgment statement in Java is very harsh, it is impossible to tolerate the above code, very strict compile time test, if the code must be the return boolean value of the
