hackerrank staircase challenge problem in Golang
问题
我想用GO语言解决Hackerrank上的这个挑战。当我运行代码时，得到的结果与挑战要求的结果相同，但他们不接受我的答案。
这是挑战链接：
https://www.hackerrank.com/challenges/staircase/problem?isFullScreen=true
这是我的代码：
func staircase(n int32) {
var i int32
for i = 0; i < n; i++ {
fmt.Println(strings.Repeat(" ", int(n-i)), strings.Repeat("#", int(i)))
}
}

I want to solve this challenge in hackerrank in GO. When I run it I get the same result as the challenge wants but they don't accept my answer.
Here is the challenge link:
https://www.hackerrank.com/challenges/staircase/problem?isFullScreen=true
Here is my code:
<!-- begin snippet: js hide: false console: true babel: false -->
<!-- language: lang-html -->
func staircase(n int32) {
var i int32
for i = 0; i < n; i++ {
fmt.Println(strings.Repeat(" ", int(n-i)), strings.Repeat("#", int(i)))
}
}
<!-- end snippet -->

首先，第一行必须有一个 # 符号，而最后一行必须有 n 个 # 符号。所以将循环改为从 1 到 n（包括 n）。
其次，fmt.Println() 在参数之间打印一个空格，这会“扭曲”输出。要么将这两个字符串连接起来，要么使用 fmt.Print()，它不会在字符串参数之间添加空格，要么使用 fmt.Printf("%s%s\n", text1, text2)。
例如：
func staircase(n int32) {
for i := int32(1); i <= n; i++ {
fmt.Println(strings.Repeat(" ", int(n-i)) + strings.Repeat("#", int(i)))
}
}
使用 staircase(4) 进行测试，输出将会是（在 Go Playground 上试一试）：

英文:
First, the first line must have one # sign, and the last must have n # signs. So change the loop to go from 1 to n inclusive.
Next, fmt.Println() prints a space between arguments, which will "distort" the output. Either concatenate the 2 strings, or use fmt.Print() which does not add spaces between string arguments, or use fmt.Printf("%s%s\n", text1, text2).
For example:
func staircase(n int32) {
for i := int32(1); i <= n; i++ {
fmt.Println(strings.Repeat(" ", int(n-i)) + strings.Repeat("#", int(i)))
}
}
Testing it with staircase(4), output will be (try it on the Go Playground):
