回文函数是一种用于判断一个字符串是否是回文的函数。回文是指正着读和倒着读都一样的字符串。在Scala中,可以使用for循环来实现一个回文函数。 下面是一个使用for循环的Scala回文函数的示例代码...
问如何在Scala for循环中使用函数ENfor循环会遍历一个值序列。常用于使用其中每个值执行某些操作。
There are various forms of for loop in Scala which are described below −Syntax for loop with rangesThe simplest syntax of for loop with ranges in Scala is −for( var x <- Range ){ statement(s); } Here, the Range could be a range of numbers and that is represented as i to j...
Scala for循环 Scala 循环 for 循环允许您编写一个执行指定次数的循环控制结构。 语法 Scala 语言中for循环的语法: for( var x <- Range ){ statement(s); } 以上语法中,Range可以是一个数字区间表示i to j,或者i until j。左箭头 <- 用于为变量 x 赋值。
递归也用于Scala库类。例如,Stream的foreach方法就是这样实现的: @tailrec override final def foreach[U](f: A => U) { if (!this.isEmpty) { f(head) tail.foreach(f) } } 将for循环转化为递归函数调用非常简单: "recursion" should "be able to replace for loop" in { // 我们可以使用递归调...
