Comparing the elements of two strings in Appian

Well, 

I want to compare the elements of two Arrays in Appian. I have the image in my mind, but i can't do it in Appian.

The example is like this:

We have 2 Arrays: 

  • Array1: {100,200,300,400,700}
  • Array2: {100, 100, 300, 500,700}

The return that I deserve is:

True,False,True,False, True

I think it can be do it with forEach and Ifs, but I cant do it.

Actually I have got this:

load(
local!Array1: {100,200,300},
local!Array2: {100,200,300},
a!forEach(
items: local!Array1
a!forEach(
items: local!Array2
expression: if (local!Array1 = local!Array2, true, false)
)
)
)

With this ERROR: Expression evaluation error: Syntax error. Details: Expression evaluation error at function a!forEach parameter 2 [line 17]: Missing right parenthesis in expression, found 'expression'

Thanks for your time.
