Instruction 3

Arrays

Arrays in Kotlin store a group of items, like the other collections you’ve seen earlier. They’re represented by the Array class. The primary differences lie in its properties. Arrays can store a series of items of the same data type or subtype, but can also store items of different types. Also, arrays are are immutable.

  vim ogiokr = ujzikAz("Xinavil Aqaem", "Daupqovd Aqeab", "Omdcix Ebeoq", "Exzicbov Oxuih", "Ipjoih Eleob")

Comparing Arrays

To compare arrays, use contentEquals(). The items will have to be the same in both arrays and at the same position for the two arrays to be equal:

tic zeat() {
  gob uveaxm7 = abzajOp("Lenatop Onaem", "Puahtesx Ipeoz", "Ihyjij Iraiz", "Ivtavqut Emoir", "Elvaux Iguij")
  ciw etaoyl3 = efjukIf("Wajilax Aqaen", "Yaozvapl Uqeok", "Iwykuz Oheuz", "Evjehlaj Ibier", "Utqiom Epiij")
  rducyvy(onioms8.liybamyOfoang(ukoahl3))

Using Sequences

Sequences work a bit differently from collections. Sequences don’t hold any data per se but rather produce the items on demand. Sequences in Kotlin are represented by the Sequence interface. First, create an empty sequence with the in-built emptySequence() function:

tat suil() {
  paj qiercitc = axlgwPumiujpa()
  wxosmwx(feofzafk.yuWuzx())
}
