Hi Stefan,

It is not related to any test. I was learning about strings in Appian and this question strike in my mind.

Thank you so much for your response.

Hi Ayushimitaal,

Use Below Code

a!localVariables(
  local!word: "apple",
  local!letters: apply(
    charat(local!word, _),
    enumerate(len(local!word)) + 1
  ),
  local!unique: union(local!letters, local!letters),
  a!flatten(
    a!forEach(
      local!unique,
      {
        fv!item & ": " & count(wherecontains(fv!item, local!letters))
      }
    )
  )
)

First, my favorite method of breaking a text into an array of texts: char(code(local!text))

Then, remove duplicate values with union, then grab the length().

local!splitText: char(code(local!text)),

length(union(local!splitText, local!splitText))

To do the second one, you need to have (or make) a split alphabet. Then a!forEach:

a!forEach(

items: local!splitAlphabet,

expression: fv!item & wherecontains(fv!item, local!splitText)

That's how I'd do it, or at least how I'd start.
