题目是这样的:
给定一个二维数组,实现一个功能函数 fn,向这个函数中传递这个二维数组的一个坐标,如果这个坐标的值为 ”1“,将返回和这个坐标所有相连的并且坐标值为1坐标。
例如,传递了 fn([3,4])得到的结果为:
[[3,4],[4,4],[5,4],[6,4],[7,4],[8,4],[8,5],[8,6]]
var arr =[
[0,0,0,0,0,0,0,0,0,0,0],
[0,0,0,0,0,0,0,0,0,0,0],
[0,0,0,0,0,0,0,0,0,0,0],
[0,0,0,0,1,0,0,0,1,0,0],
[0,0,0,0,1,0,0,0,1,0,0],
[0,0,0,0,1,0,0,0,1,0,0],
[0,0,0,0,1,0,0,0,0,0,0],
[0,0,0,0,1,0,0,0,0,0,0],
[0,0,0,0,1,1,1,0,0,0,0],
[0,0,0,0,0,0,0,0,0,0,0],
[0,0,0,0,0,0,0,0,0,0,0],
] ;
