The downTo() function is used for creating a range in descending order i.e., from the given larger value to the smaller value. The downTo() function is the reverse of the (..) operator and rangeTo() function.
Here, we will demonstrate the example of creating a character range using the downTo() function.
fun main(args : Array<String>){
// creating character ranges
// in descending order
println("Character range 1:")
for(x in 'g'.downTo('a')){
println(x)
}
println()
println("Character range 2:")
for(x in 'p'.downTo('g')){
println(x)
}
println()
}
Output:
Character range 1:
g
f
e
d
c
b
a
Character range 2:
p
o
n
m
l
k
j
i
h
g
Example 2:
fun main(args : Array<String>){
// creating character ranges
// in descending order
println("Character range 1:")
for(x in 'g'.downTo('a') step 3){
println(x)
}
println()
println("Character range 2:")
for(x in 'p'.downTo('g') step 3){
println(x)
}
println()
}
Output:
Character range 1:
g
d
a
Character range 2:
p
m
j
g
