发帖数: 391 | 3 今天面试码工职位,被问到了一道coding题，说有一个m x n的二维矩阵Item[][]，每一
个元素都是一个Item类的object， 其中Item类定义如下:
public class Item{
public int x; //
public int y;
}
x和y分别是矩阵里的另一个元素的横纵坐标。实现一个函数，给定一个起始点的横纵坐
标startX 和startY，返回从起始点出发的traversal是否能cover矩阵里的每一个点。
我的想法是用一个hashSet，每初始化一个Item，都放入这个set， 直到遇到重复元素
或null为止，然后计算hashSet的size是否等于matrix的size。我写的基本算法:
boolean getCoverage(Item[][] items, int startX, int startY){
Item item = items[startX][starty];
HashSet- set = new HashSet
- ();
set.add(item);
while(item... 阅读全帖 |

public static BigInteger reach(char start, char end, int steps) {
Map keyboard = new TreeMap<>();
Map pathsMap = new HashMap<>();
keyboard.put('1', new int[] { 0, 0 });
keyboard.put('2', new int[] { 0, 1 });
keyboard.put('3', new int[] { 0, 2 });
keyboard.put('4', new int[] { 1, 0 });
keyboard.put('5', new int[] { 1, 1 });
keyboard.put('6', new int[] { 1, 2 });

这样一个方法？ |

发帖数: 799 | 9 保证startX < endX; startY < end Y;
然后两层for循环不就完了吗？

发帖数: 543 | 20 that's true for what i posted here....
but actually Im facing a more complicated situation. I have also other
variables, such as something like match_key. So once I need to keep track of
the original order....
Or probably I should change the way of posting the problem as we have
original data set:
Var1
A_1
A_2
B_1
B_2
B_3
C_1
C_2
C_3
...
and Im still trying to do the same thing as randomly pick 1 number from 1,2,
3 to assign to var1, while this can not be the same number for Var1 starti |
