Hi,

Dear folks,

Here is what i want to do and thankfully was able to get answer using thread below with List
https://developer.salesforce.com/forums/ForumsMain?id=9062I000000BjjoQAC
,but now i am rewriting the same code using Map,but am getting error as 
 

Method does not exist or incorrect signature: void get(String) from the type Map

Here is what the end goal is 
 

For example, if s = "zbax" and k = 2, then the resulting integer would be 8 by the following operations:

Convert: "zbax" ➝ "(26)(2)(1)(24)" ➝ "262124" ➝ 262124
Transform #1: 262124 ➝ 2 + 6 + 2 + 1 + 2 + 4 ➝ 17
Transform #2: 17 ➝ 1 + 7 ➝ 8

Here is code with Map

public class SDASMapConvert {
    

    
    
public static Integer returnInteger(String z, integer k){
        Integer retInt;
        String key = 'abcdefghijklmnopqrstuvwxyz';

        List<String>myAlphabets = z.split('');
        Map<String, String> myMap = new Map<String, String>();
        String strarr = '';

       for (integer i = 0; i < myAlphabets.size(); i += 2) {
        myMap.put(myAlphabets[i], myAlphabets[i + 1]);
    }

    for (String s : myMap.keySet()) {
        System.debug(s + ' is ' + map.get(s));
        strarr += string.valueOf(s);
    }
        
        system.debug('strarr --> ' + strarr);
        String s = '';
        for(integer i = 0; i < k ; i++){
            system.debug(' strarr --> ' + strarr);
            Integer total = 0;
            for(String s1 : strarr.split('')){
                total += integer.valueOf(s1);
            }
            system.debug(' total --> ' + total);
            strarr = string.valueOf(total);
        }
        
        system.debug(' ************* ' + strarr);
        if(!string.isEmpty(strarr))
            retInt = integer.valueOf(strarr);
        
        system.debug(' ************* ' + retInt);
        
        return retInt;
    }
    


}
