noncollision

代码说明：

  实现4×4的数组元素的无冲突的存储，该算法不使用结构体，而直接使用了数组元素与下标之间的关系实现，比较巧妙，16×16可参照类似算法实现。(Realize 4 × 4 array of elements of the conflict-free storage, the algorithm does not use the structure, while the direct use of the array elements and the relationship between the subscript realize, more subtly, 16 × 16 can be the light of a similar algorithm.)
