-When working with long strings, it is most convenient to use so-called [multiline strings](https://kotlinlang.org/docs/coding-conventions.html#strings).

 ### 2. The `trimIndent` and `trimMargin` functions
 
-For convenient work with such strings, there are two functions: [`trimIndent`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.text/trim-indent.html) and [`trimMargin`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.text/trim-margin.html).

 In the first case, the string will have extra indents and margins.
 Also, each line in the string has the `*` symbol.
 In the second case, the string looks better, but it still has an extra symbol in each line.
