下午去打了个酱油,就做出一道最简单的题,2048游戏,实在是太菜了,马上要找工作了,复习的不到位啊! 解法: k记录要被放置的位置索引 1.k位置元素是0,将e[i]移到e[k] 2.k位置非零: (1)e[i]==e[k]相同,碰撞,e[k]×=2,k移到下一个位置(k或--k) (2

下午去打了个酱油,就做出一道最简单的题,2048游戏,实在是太菜了,马上要找工作了,复习的不到位啊!


解法:

k记录要被放置的位置索引
1.k位置元素是0,将e[i]移到e[k]
2.k位置非零:
  (1)e[i]==e[k]相同,碰撞,e[k]×=2,k移到下一个位置(++k或--k)
  (2)e[i]!=e[k]不同,k移到下一个位置(++k或--k),将e[i]移到e[k]

复杂度O(n^2),代码有点乱,没整理,如下:

#include <iostream>
#include <string>
inline void arrayMove(short (*val)[21],int n,std::string&dir){
	if(dir=="up"){
		for(int j=0;j<n int k="0;" for i="1;i<=n-1;++i){" if continue val j="0;j<n;++j){">=0;--i){
				if(0==val[i][j])
					continue;
				if(0==val[k][j]){
					val[k][j]=val[i][j];
					val[i][j]=0;
				}else if(val[i][j]==val[k][j]){
					val[k][j]=val[i][j]=0;--j){
				if(0==val[i][j])
					continue;
				if(0==val[i][k]){
					val[i][k]=val[i][j];
					val[i][j]=0;
				}else if(val[i][j]==val[i][k]){
					val[i][k]=val[i][j]>T;
	while(++i>N;
		std::cin>>dir;
		for(int j=0;j<n for k="0;k<N;++k)" std::cin>>val[j][k];
		
		arrayMove(val,N,dir);
		std::cout<br>
<br>
