Characters¶
You’re interested in figuring out the number of case-insensitive unique characters in some string. This sounds simple and easily-automated, so you just decide to just go for it.
Input¶
Your input will consist of an integer N followed by a newline. N test cases will follow, all separated by newlines. Each test case is a string of letters containing some combination of letters (upper- and lower-case are allowed), the space character, and the characters contained in the string ?!.’$%&*:;,.
Output¶
Your output should consist of one integer per case, separated by whitespace, indicating the number of case-insensitive unique characters contained in the input string.
