kotlin to sorted map reverse
To sort a map in reverse order using Kotlin, you can follow these steps:
Create a
Map
object with key-value pairs. For example:kotlin val map = mapOf("a" to 1, "b" to 2, "c" to 3)
Use the
toSortedMap
function to create a sorted map. ThetoSortedMap
function takes aComparator
as an optional argument. In this case, we'll use theComparator.reverseOrder()
method to sort the map in reverse order.kotlin val sortedMap = map.toSortedMap(Comparator.reverseOrder())
Print the sorted map to see the result.
kotlin println(sortedMap)
Here's the complete example:
val map = mapOf("a" to 1, "b" to 2, "c" to 3)
val sortedMap = map.toSortedMap(Comparator.reverseOrder())
println(sortedMap)
Output:
{c=3, b=2, a=1}
This code will create a map with key-value pairs, sort it in reverse order using toSortedMap
, and then print the sorted map. The output will show the sorted map in reverse order.
