scala中写for循环

Scala | 带多个计数器的for循环 (Scala | for loop with multiple counters)

For loop is used to iterate over a block of code multiple times until a given condition is true. It is a counter-based loop that runs n times specified by a range.

For循环用于多次遍历代码块，直到给定条件为真。 这是一个基于计数器的循环，运行一次由范围指定的n次。

In programming, their might arise cases where you need to iterate keeping in mind multiple counters (also known as generators in Scala) like in case of working with a multidimensional array.

在编程中，可能会出现这种情况，您需要反复记住多个计数器(在Scala中也称为生成器)，就像在使用多维数组的情况下一样。

Here, is how to use for loop with multiple counters? It's a simple method, you just need to use two variables instead of one.

在这里， 如何使用带有多个计数器的for循环 ？ 这是一种简单的方法，您只需要使用两个变量即可 。
