Here to share a piece of code on the jquery pop-up div layer and automatically disappear the implementation code, nonsense said, the specific code is as follows: var huifang={ m_tishi:null,//global variable to determine if a div exists, //prompt Div to wait 2 seconds to automatically close funtishi:function (co

We often go into a misunderstanding, will think that in the Web2.0 era, as long as the page is no technical content, is a disgrace, if the page does not have a table, all elements of the div to do, that is the cow! Everyone, if someone says to you that my entire site doesn't apply a table, then you can think that this person does not have any technical content on the page We went on to last class, continue

A Group is either one person who can write the contest with anyone else, or both people who want to write the contest in th E same team.

Each of the next K lines contains the description of exactly one query:1 ri ai (1≤ri≤n, 1≤ai≤109), means that row RI is painted in color AI; 2 ci ai (1≤ci≤m, 1≤ai≤109), means that column ci are painted in color AI. Output Print n lines containing m integers each-the resulting table after all operations are. Examples input 3
