Is there a base function or simple way to replace multiple strings with multiple strings in a reference String?
I have seen Replace multiple strings with multiple other strings but it is using known lists instead of variable ones.
For example:
I have val str = "THE GOAT IS RED" , and I want to replace all the characters with other characters or digits, something like:
str.replace("THEGOAISRD".toList(), "0123456789".toList())
To which will result
"012 3450 67 829"
val list1 = listOf('a', 'b', 'c')
val list2 = listOf('0', '1', '2')
val str = "abacada"
val transform = list1.withIndex().associate { it.value to list2[it.index] }
val result = str.map { transform[it] ?: it }.joinToString(separator = "")
println(result)
prints 01020d0
transform = list1.zip(list2).toMap(). This even lets you skip the step of converting them to lists: transform = "abc".zip("012").toMap().You could do that by first building a dictionary (Map<Char, Char>) using zip and then iterating the string to transform with joinToString like that:
val str = "THE GOAT IS RED"
val dictionary = "THEGOAISRD".zip("0123475689").toMap()
val result = str.toCharArray().joinToString("") {
dictionary.getOrDefault(it, it).toString()
}
println(result)
