# Fill out my Bubble Sheet

Today was AP exam registration day at my school, and while I was meticulously bubbling in the pages and pages of information required, the idea for this challenge hit me. So, given a string of letters and numbers, output an appropriately filled out bubble chart.

# Rules:

• For each character in the input string, replace that character in the corresponding column with a # or @ or any other reasonable symbol (if your language can handle it, the Unicode character 'full_block': █ looks really good)
• A space is represented by a blank column (see examples)
• Valid input will be a string which is made up of only uppercase letters, numerical digits, and spaces.
• Input will be of a length with a minimum of 1, and a maximum of 32 characters.
• Output must be UPPERCASE
• If the input length is less than the maximum length of 32, your program must still output the remaining blank columns
• Your program doesn’t have to handle lowercase input the same as if they were uppercase, but bonus points if it can.

And of course, this is , so shortest answer wins

• Input validation is generally discouraged, so you could just have the input match [A-Z0-9]{1,32} and allow any behavior for inputs not matching that. – Giuseppe Apr 20 '18 at 17:44
• How ridiculously annoying is the fact that '0' comes before 'A' in ASCII code >:( lol – NL628 Apr 20 '18 at 18:00
• "Valid input will be a string which is made up of the characters that appear on the bubble sheet as well as spaces" but you also state "Any character other than the capital letters, spaces, and numerical digits, or over the 32 character limit should be ignored", so which one is it? – user41805 Apr 20 '18 at 18:55

".(++$c<B&&$c=0):█;


++$c<B is false for all letters up to Z and for all non-negative numbers. Z incremented is AA; in that case $c is set to 0 to loop through the digits.
&& casts the whole expression to false, . casts that to the empty string.
