Поиск и сортировка

Линейный поиск

constant DecimalNumber Arr = new DecimalNumber[] {0.25, 1.0, 2.0, 0.5, 1.0}
WholeNumber i = 0
DecimalNumber X = this.getDoubleFromUser("X")
while (i < Arr.Length) is true
{
  if (X == Arr[i]) is true then
  {
    this.alice  say "X найден в позиции " + i
    i = Arr.Length
  }
  else
    i = i + 1
}
if (i == Arr.Length) is true then
  this.alice  say "X не найден"
