最近在学Go语言...
你看看这个和第一篇题解一模一样，为啥就是不对列
被卡精度了吗？？？
package main
import "fmt"
func main() {
n := 0
var k int
fmt.Scanf("%d", &k)
for Sn := 0.0; Sn <= float64(k); n, Sn = n+1, Sn+1.0/float64(n) {
}
fmt.Println(n)
}

与题解一模一样（我发现了什么）

这份代码可以通过
package main
import "fmt"
func main() {
n := 0
Sn := 0.0
var k int
fmt.Scanf("%d", &k)
for Sn <= float64(k)+0.000001 {
n = n + 1
Sn = Sn + 1.0/float64(n)
}
fmt.Println(n)
}

n, Sn = n+1, Sn+1.0/float64(n)这句话出现了问题，float64(n)里的n并没有变成n+1，导致Sn变成了+INF
