Kotlin Range FAQs
A closed range (e.g., 1..5) includes both the start and end values. An open or half-open range (e.g., 1 until 5) includes the start value but excludes the end value.
Yes, you can create ranges with custom types as long as those types support comparison operations (<, <=, >, >=). You can define how comparisons work for your custom types by implementing the necessary comparison operators.
You can use the filter or filterNot functions to filter values within a range based on a condition. These functions return a new range with the filtered values.
No, ranges in Kotlin are immutable. Once created, you cannot change their start or end values. If you need a mutable sequence of values, you should use a list or another data structure.
Yes, you can create ranges with floating-point numbers (e.g., Float or Double) in Kotlin using the same range creation methods as with integers.
