题目：

实现这样的方法： 可以动态创建一个二维Array, 内容如下

generate_array(3)

获得：

[

[ha],

[ha,ha],

[ha,ha,ha],

]

 再如：

generate_array(4)

获得：

[

[Anna],

[Anna,Anna],

[Anna,Anna, Anna],

[Anna,Anna, Anna,Anna],

]

代码1(带日志)：

package main

import (
  "fmt"
)

func generate_small_array(n int, name string) []string{
  // 第一次循环
  result := []string{}
  for i := 1; i <= n; i++{
    result = append(result, name)
    fmt.Println("====== 每个循环1, i:", i, "result", result)
  }
  fmt.Println(result)
  return result
}

func main() {
  // 第二次循环
  result := [][]string{}
  for i := 1; i <= 3; i++{
    result = append(result, generate_small_array(i, "haha"))
    fmt.Println("====== 每个循环2, i:", i, "result", result)
  }
  fmt.Println(result)
}

结果:

====== 每个循环1, i: 1 result [haha]
[haha]
====== 每个循环2, i: 1 result [[haha]]
====== 每个循环1, i: 1 result [haha]
====== 每个循环1, i: 2 result [haha haha]
[haha haha]
====== 每个循环2, i: 2 result [[haha] [haha haha]]
====== 每个循环1, i: 1 result [haha]
====== 每个循环1, i: 2 result [haha haha]
====== 每个循环1, i: 3 result [haha haha haha]
[haha haha haha]
====== 每个循环2, i: 3 result [[haha] [haha haha] [haha haha haha]]
[[haha] [haha haha] [haha haha haha]]

代码2:

package main
import "fmt"
func sort_array(m int, n string) []string{
  var name = []string{}
  for i := 1; i <= m; i++{
    name = append(name, n)
    fmt.Println("name:", name)
  }
  fmt.Println(name)
  return name
}
func main() {
  var name = [][]string{}
  for i := 1; i <= 3; i++{
      name = append(name, sort_array(i,"Anna"))
      fmt.Println("i:", i,"name1:", name)
  }
  fmt.Println("name2:", name)
}

结果:

name: [Anna]
[Anna]
i: 1 name1: [[Anna]]
name: [Anna]
name: [Anna Anna]
[Anna Anna]
i: 2 name1: [[Anna] [Anna Anna]]
name: [Anna]
name: [Anna Anna]
name: [Anna Anna Anna]
[Anna Anna Anna]
i: 3 name1: [[Anna] [Anna Anna] [Anna Anna Anna]]
name2: [[Anna] [Anna Anna] [Anna Anna Anna]]
