Hello,

Trying to get my head around this. If I have a word string that can contain any word how can I return a variable that provides the number of different letters contained in that word.

Example:

var number_of_different_letters;

string myword = "potatoe"; // the word
string myword2 = "rocket"; // another word

Is it possible to assign the number of different letters from these strings into the variable number_of_different_letters?


So for

myword: number_of_different_letters = 5; since there are 2 instances of t and 0

myword2: number_of_different_letters = 6;// all different letters


Would appreciate any help.

best regards,

Rob
