Hi hope this is the right place I am trying to loop through

Question

Hi hope this is the right place I am trying to loop through a list of Strings so that I can create an array called Letter which is made of a String and an Int The problem is that whatever I do I only ever get the last value of my list of Strings What could I be doing wrong ``` fun savedData Array lt Letter gt val arr = mutableStateOf boardLetters if savedValues = null for item in savedLetters arr value = Array 28 Letter item 0 return arr value ``` For info boardLetters is this `boardLetters Array lt Letter gt ` Thanks for any help

The problem is that you assign `arr value` to an array for each `savedLetters` so you replace the array each iteration keeping the last in the end

I m guessing what you want is something like ```fun savedData Array lt Letter gt return savedValues map Letter it 0 toTypedArray arrayOf ```

I also have a list of savedValues for each savedLetters How can I add them instead of the 0

Luke · Answer

`savedValues` is a list with corresponding index a map or something else

```fun savedData savedLetters List lt String gt savedValues List lt Letter gt List lt Letter gt return savedLetters map l gt Letter l savedValues find it letter == l value 0 ```

nkiesel · Answer

or better if savedValues can become long ```fun savedData savedLetters List lt String gt savedValues List lt Letter gt List lt Letter gt val m = savedValues associateBy Letter letter return savedLetters map l gt m getOrDefault l Letter l 0 ```

Thanks a lot I m in a call but will check it out after Cheers slightly smiling face

nkiesel · Answer

```fun savedData savedLetters List lt String gt savedValues List lt Letter gt List lt Letter gt return with savedValues associateBy Letter letter savedLetters map get it Letter it 0 ``` if you like one liners

nkiesel · Answer

note that this assumes that `Letter` is immutable If that is not the case you must return new letters ```fun savedData savedLetters List lt String gt savedValues List lt Letter gt List lt Letter gt return with savedValues associateBy Letter letter savedLetters map Letter it get it value 0 ```
