the element triggers the onmousedown event, I register the onmousemove and onmouseup events directly on the document, so that there will be focus when you move the cursor anywhere. After that, let's look at the code structure! The Code is as follows: Drag = {Obj: null,Init: function (options ){Options. handler. onmousedown = this. start;Options. handler. root = options. root | options. handler;Var root = options. handler. root;Root. onDragStart = options. dragStart | new Function ();Root. on

Purpose: The UI responds to the scrolling up or down of the screen. Initial implementation: 1 var scrollfunc = function (e) {2 3 var DATA = 0; 4 E = E | window. event; 5 If (E. wheeldelta) {// IE/Opera/chrome 6 data = E. wheeldelta; 7} else if (E. detail) {// Firefox 8 Data = E. detail; 9} 10 CB CB (data); 11} 12/* Registration event */13 if (document. addeventlistener) {14 document. addeventlistener ('domainscroll', scrollfunc, false); 15} 16 window. onmousewheel = document. onmousewheel = scr

is certain, then, you can advancedThe number of steps required for each move of the target piece under the above conditions is preprocessed. Then, after the preprocessing is complete, we will find that each query becomes a shortest-circuiting problem, which can be resolved within the timeframe by Dijstra or SPFA. (SPFA better)Realize:Define an array f[x][y][k][h], indicating the target piece in position (x, y) and the space in the direction of the target piece in the K-orientation of the adjace

situation One:The function appears in an infinite loop in the following two-sentence code:while (ABS (SX-LP.X1) + ABS (SY-LP.Y1) > Lp2.len){SX = (lp.x1 + sx) >> 1;Sy = (lp.y1 + sy) >> 1;}When debugging a breakpoint, the result of an infinite loop is that the value appears as follows:Sx=0x3d00Lp.x1=0x3d01Sy=0x7a00Lp.y1=0x7a01Lp2.len=1in this case, SX and the Sy value is never changed, and the condition of the loop is always set ( While (2>1).Try modifying the following:SX = lp.x1 + ((sx-lp.x1) >>

figure, the shortest path is the black part, now go to the red part, then go out and walk back to the shortest part of the path is the red part, why not count the blue, because if the red is removed, the blue part of the translation is the shortest path!! So, if you want to go to the end of the T-step, the more part must be an even number (T-min steps) must be even, so we can prune!1#include 2#include 3#include 4 using namespacestd;5 Charmap[8][8];6 intM,n,bx,by,ex,
