Hi,

Is there any straightforward method to compare below two arrays in such a way that, SelectedAnswersArray[1]=correctAnswersArray[1] , SelectedAnswersArray[2]=correctAnswersArray[2] and SelectedAnswersArray[3]=correctAnswersArray[3] .

SelectedAnswersArray: {"a","c","b"}

correctAnswersArray: {"a","b","c"}

{"a","c","b"}={"a","b","c"}

As unreal as it looks, just an equal operator will work.

Did you try a simple foreach() that compares the values on both lists by index? This will get you a list of booleans.

Can we use foreach() inside a foreach() ?

stefanhelzle0001

Sure, but why would you want to do that?

Hi,
Adding to Harshit's and Stefan's comments, you can also use Appian's OOTB function 'exact', which will help you, in case you need to compare in a case-sensitive manner.

a!forEach(
  items: merge({ "a", "B", "C" }, { "a", "b", "C" }),
  expression: exact(fv!item[1], fv!item[2])
)

Comparing two arrays returns a list of booleans. This might be a little better:

a!localVariables(
  local!array1: { 1, 2, 3 },
  local!array2: { 1, 2, 3 },
  not(contains(local!array1 = local!array2, false))
)

Hello [mention:effa9f429a764d98b42411e7f964ed12:e9ed411860ed4f2ba0265705b8793d05] ,

You can try this as well.

a!localVariables(
  local!arr1:{1,2,4},
  local!arr2:{1,2,3},
  a!forEach(
    items: local!arr1,
    expression:fv!item=local!arr2[fv!index]
  )
)
