我正在嘗試在 Kotlin 中列印串列的所有組合。
我的腳本有一個帶有加密訊息的可變訊息。我想要的是該變數的所有組合（在空間上拆分）。我已經設法在空間上分割它，所以它變成了一個字串串列。
所需輸出的示例：

等等..
我的代碼：
// Input data
var message: String = "Y2MPyYU4kblEXrEfExry4AIRAjqdke JyQQN50Uj5GuCu5rE66lEzQXB5bE VOlNGRoU06Ny4vh/gzSPFV0mHUrxaaAVt1BwN1WN1HFT7baIejtR5KyG6 JK8yC70CpuPZV610coCiWzdFICcgEtAdQaesScLrg495kxofzG3EGvA="
// Info Message
var messageLength = message.length
println("Message = $message\n")
// Info parts
var messageSplitOnSpace = message.split(" ")
for (part in messageSplitOnSpace) {
var partLength = part.length
println("Part = $part\n")
}
// Print all combinations
var mixSize: Int = messageSplitOnSpace.size*messageSplitOnSpace.size;
for (part in messageSplitOnSpace) {
}
