题目是: 给定一个自然数n，将n*n个数字按顺时针方向填入一个二维数组, 比如: n=4, 则结果为:

1  2  3   4
12 13 14  5
11 16 15  6
10 9  8   7


const count = 4
const result = []
for (let i = 0; i < count; i++){
  result[i] = Array(count).fill(0)
}

for (let i = 0; i < count; i++){
  for (let j = 0; j < count; j++) {
    const round = Math.min(i, j, count - 1 - j, count - 1 - i)
    if (i <= j){
      result[i][j] =  i + j + 1 + (count * round - round * round) * 4 - round*2
    }else{
      result[i][j] =  (count * (round + 1) - (round + 1) * (round + 1)) * 4 - (i + j - 1) + round*2
    }
  }
}

result.forEach(row=>{
  console.log(row.join('\t'))
})
