Find Missing Letters

Hello… Guys…
i can found missing letter in Intermediate Algorithm Scripting: Missing letters challenge…
but it would print only missing letter and i want to print all letters with missing letter…
How can i do it?
Please Help me…
Ex. function find(“abce”); // return “d”;
but i want “abcde”;

Go head and post your code and a link to the exercise.

It is just for your own version of the challenge right? Because the challenge does not ask you to return the full string.

If you know what letter is missing and where it is missing, then it shouldn’t be too hard to concatenate the string to include the letter. How you would do it depends on the solution you have for the challenge.

What have you tried and do you have some code you can post?
