Displaying multiples of 5 from 1-100, include every value which is having number "5"

a!localVariables(
local!sample:a!forEach(
items: enumerate(100)+1,
expression: {if(find(5,fv!index,1),fv!index,{}),
if(mod(fv!index,5),{},fv!index)
}
),
local!data:union(local!sample,local!sample),
local!data
)

a!localVariables(
  local!data:enumerate(100)+1,
  local!5divisons:{if(mod(local!data,5),{},local!data),if(find(5,local!data),local!data,{})},
  local!un:union(local!5divisons,local!5divisons),
  remove(local!un,1),
),

Once try this code 

I didn't get the exact output But helpful

a!localVariables(
  local!data:a!forEach(
    items: enumerate(100)+1,
    expression: {if(mod(fv!index,5),{},fv!item),if(find(5,fv!item),fv!item,{})}
  ),
  union(local!data,local!data)
)

once try this

a!forEach(
items: enumerate(100),
expression: {
if(
mod(fv!item,5),
{},
fv!item
)
}
)

(enumerate(20) + 1)*5

Very interesting to see different ways to do it. However I liked this one most.

a!forEach(
  items: enumerate(100)+1,
  expression: if(or(
    mod(fv!item,5)=0,
    find(5,fv!item)<>0
  ),
  fv!item,
  {}
  )

)

a!localVariables(
  local!data: a!forEach(
    items: enumerate(100)+1,
    expression: append(if(find(5,fv!item),fv!item,{}),if(mod(fv!item,5),{},fv!item)),
  ),
  local!uniqueData:union(local!data,local!data),
  local!uniqueData
)
