How to iterate through a string

a!localVariables(
  local!string: "harshitbumb.com",
  local!charArray: char(code(local!string)),
  a!forEach(
    items: union(local!charArray,local!charArray),
    expression: {
      character: fv!item,
      count: count(wherecontains(fv!item,local!charArray))
    }
  )
)

Thank you very much sir .

Sir how to find median of an array containing integer elements without using median () method ?

Why do you want to do it without the method?

a!localVariables(
  local!input: "TECHNOLOGY",
  a!forEach(
    items: char(code(local!input)),
    expression: fv!item  & " "& len(cleanwith(local!input,fv!item))
  )
)

a!localVariables(
local!string: "technology",
union(
a!forEach(
items: enumerate(len(local!string)) ,
expression: {
a!localVariables(
local!char: regexallmatches(
local!string[fv!index],
local!string,
"gms"
),
local!char[1] & " - " & length(local!char)
)
}
),
{}
)
)

a!localVariables(
  local!cahrArr:code("hello"),
  a!forEach(
    items:union(local!cahrArr,local!cahrArr) ,
    expression: concat(char(fv!item)," - ",length(wherecontains(fv!item,local!cahrArr)))
  )
)
