就闭包而言,这里有一个明显的不同,这次flatMap期望一个(Wrapped) -> U?)闭包。对于可选值, flatMap 对于输入一个可选值时应用闭包返回一个可选值,之后这个结果会被压平,也就是返回一个解包后的结果。本质上,相比map,flatMap也就是在可选值层做了一个解包。 varvalue:String? ="1"varresult =value.map...

在Go 语言中,浮点类型(float32和float64)可以作为 map 的键(key),但这并不是一个好的实践。原因在于浮点数的精度问题和比较的复杂性。 浮点数的比较可能会引入微小的误差,这可能导致意料之外的结果。即使两个浮点数看起来相等,但由于精度问题,它们可能在内存中的表示是不同的。这就意味着,即使你使用看似相同的...
