題目是這樣的：給定一個(gè)二維數(shù)組，實(shí)現(xiàn)一個(gè)功能函數(shù) fn，向這個(gè)函數(shù)中傳遞這個(gè)二維數(shù)組的一個(gè)坐標(biāo)，如果這個(gè)坐標(biāo)的值為 ”1“，將返回和這個(gè)坐標(biāo)所有相連的并且坐標(biāo)值為1坐標(biāo)。例如,傳遞了 fn([3,4])得到的結(jié)果為：[[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],] ;
