Product attributes and product specifications are the elements dynamically generated by JS. The two text boxes of product extension information are original elements, which are stacked, I thought it was because the size of the DIV where the generated element is located is not fixed, because the check boxes below the product specification are generated by the second Ajax, I doubt whether Ajax cannot push the original elements of the page down to a prop
Topic: Given n nodes, each node has an initial weight, maintaining the following operations:1. Consolidation of two unicom blocks2. A certain point weight value +x3. The right value of the Unicom block at a certain point +x4. Some weight value +x5. Ask for the weight of a point6. Ask for the maximum weight of the Unicom block at a point7. Ask for the maximum weight between all points233333333333333333333333333333333333333333333333333333333333323333333333333333333333333333333333333333333333333333
value of the node is less than or equal to the key value of its left and right child nodes.[Property 2] The distance of the left child node of the node is not less than the distance of the right child node.[Property 3] The left child node of the node is also a left-biased tree.Code#include #include#include#include#includeusing namespacestd;intRead () {intx=0, f=1;CharCh=GetChar (); while(ch'0'|| Ch>'9') {if(ch=='-') f=-1; Ch=GetChar ();} while(ch>='0' ch'9') {x=x*Ten+ch-'0'; Ch=GetChar ();} r

Since 2 ninjas were dispatched and the manager's leadership was 3,User satisfaction is 2, is the maximum number of user satisfaction can be obtained.SolutionThis is the strategy.Solution optimality: When the whole tree is DFS, we actually enumerate each manager, take the bestand solve the problem of optimali

When a floating couplet advertisement is added to the page, the Flash has a stacked effect. The final cause is the onscroll event, and a setTimeout delay is added to solve the problem.Originally:
Function scall (){.......}Window. onresize = scall;Window. onload = scall;
Now:
Function scall (){.......}Function scalltime (){Window. setTimeout ("scall ()", 1 );}Window. onscroll = scalltime;Window. onresize = scalltime;Window. onload = scalltime;
