Lame frog note 19-cocos2d-x-3.2 screen lock genie Movement Previous review In the previous article, he learned how to use OrbitCamera and learned about it. Although the parameters in the OrbitCamera: create Function are difficult to understand, we can explain them in an abstract way. Haha, this time I learned how to lock the running of the genie with the screen. Introduction First, let's look at the inheritance relationship as follows. Follow direc

Question: Chinese question...Idea: it is easy to understand from the question, posx + vx * t-posy-vy * t = k * L, that is, the solution to this equation. After simplification, the equation can be written as t * (vx-vy)-k * L = posy-posx, and further reduced to k * L + t * (vy-vx) = posx-posy, L and (vx-vy) can be obtained, that is, known. This equation is a common form of Extended Euclidean equation that we are familiar.In this case, gcdx = gcd (L, vy-vx). If (posx-posy) % gcdx = 0, the equation

by gcd (A, A, a), we can find the Ax+by=1 x and y, but we want the solution of ax+by=c, so at the same time multiply C, where the uppercase letter is to represent about GCD (A, b) after the equation. Then the solution of this equation is x0=tx*c+b*k. Y0=ty*c-a*k. K is { -1,-2,0,1,2} and so on.int get_min_number (int a,int b,int c,int x,int y)//Minimum integer solution to get A*x+b*y=c{int ABGCD = GCD (A, b);if (C%ABGCD! = 0) return-1;//no solutiona/= abgcd; b/= ABGCD; C/= ABGCD;int tx,ty;EXGCD

Test Instructions: It is known that the starting position of 2 frogs, A, b, and the distance jumping once m,n, now they are jumping in the same direction along a line of latitude (circle) of length L. Ask when they will meet? (Well, there's a talk of frogs (?????? ‵) *) will never meet and output "impossible". (Stupid-_-!)Solution: The least positive integer solution of the congruence equation is obtained by expanding Euclid. (A+MX)-(B+NX) =k*l (k = number of laps) → (m-n) x=k*l+b-a→ (m-n) x=b-a

The extension of Euclid is very classic, but sometimes it is very difficult to use. Some things suddenly do not understand.Then came an inverse-day template. As long as you can list ax+by=c, you can solve the x>=bound of a group of solutions ~ll EXGCD (ll A, ll B, LL x, ll y) { if (b = = 0) { x = 1; y = 0; return A; } LL r = exgcd (b, a% B, x, y); LL t = y; y = x-a/b * y; x = t; return r;} /* can get X>=bound x and Y, return true to indicate there is no solutio

Topic Links:http://poj.org/problem?id=1061Main topic:Chinese topic, test instructions at a glance, is the data range is surprisingly large.Problem Solving Ideas:Assuming that two frogs have skipped T-times, you can list the indefinite equation: P*l + (n-m) *t = = x-Y. After the equation is listed, the solution of the indefinite equation is calculated using the extended Euclidean. In finding the smallest solution of the whole place card for a long time, long.To learn more about the use and proof

I. Question Poj 1061 frog appointment [Questions about "Euclidean for maximum common approx." and "Extended Euclidean algorithm] Ii. Source Project # Include Iii. Solutions It takes the same time for the two frogs to jump once. If we set it to t, x + MT is the distance from the coordinate origin to the end, and Y + nt is the distance from B, to meet each other, the subtraction must be an integer multiple of the perimeter of the ground, set to K * l;

There is nothing to say. Find out the formula, first find a group of special solutions, and finally obtain the desired solutions... Train of Thought: Set up a frog to jump X times before meeting, get the equation (a + XM) % L = (B + Xn) % L to release X (m-N) + yl = B-. according to the Extended Euclidean algorithm, a group of solutions of X (m-n) + yl = gcd (m-N, L) can be obtained, When (B-A) is a multiple of gcd (m-N, L), the original equation has

// Frog recommendation: demonstrate index indicator usage (C #)// This example shows the number of vertices in a continuous natural number. In addition to 1, the prime number can be divisible by 1 and cannot be divisible by others.// Sorry, when I was a child, I was not familiar with mathematics. I didn't understand how to judge the prime number algorithm. However, this does not affect the creation and use of index indicators. Who knows, please give m

Frog: the difference between the match method and the exec method in js is a bit dizzy. Let's explain how it works. First, let's look at the first piece of code. This section uses the Match method of the String object. Three Links can be displayed, indicating that the matching is normal, but the (. | \ n )*?) And (.*?) I don't know what the difference is. Let's take a look at the second program. here only two dialogs are displayed, and the last one is
