# 2016 Time Capsule String: Coverage

Consider the 74 characters from the 2016 time capsule string (note the leading space):

 !!!!!#$$%&())))*+...1449:=@@@AHILOQQQTTZ\\^eefmpxy{||||~~~~~~~~~  Your task is to write as many programs as possible (in the same language) using these characters. The output of each program must be nonempty. When all of the programs and their outputs are considered, it must only use each of the 74 above characters no more than once. Your score is determined by the number of programs you have written, with the total length of the programs being a tie-breaker (greatest length wins). Some more rules: 1. Each program must terminate. 2. Each program must be a full program and output in a reasonable format. 3. All output to STDERR is ignored. 4. You may not run your program with any flags, except those required to run the program. (E.g., a -e flag that executes program source.) 5. If the program has output that cannot be suppressed, you may ignore when considering the output. (E.g., you may ignore trailing newlines.) 6. Each program should be able to be executed with empty stdin. ## Example If I had programs 4 and T1~ that outputted 4 and 9 respectively, they would, when considered together, be: 44T1~9  Which can be seen to be a subset of the capsule string. However, if I had programs 4@|4 and |e+ that outputted 4 and f respectively, they would be: 4@|44|e+f  And, since there are 3 4s, it is not a subset. • Can be disregard ans = .. in the output from MATLAB? That's allowed by default, except for challenges like "Hello, world" and other challenges with a very strict format. – Stewie Griffin Mar 28 '17 at 11:18 • Programs are not expected to produce different outputs, or be different themselves, are they? – Fatalize Mar 28 '17 at 11:26 • @StewieGriffin Yes, you can, I'll edit to reflect this. – Conor O'Brien Mar 28 '17 at 15:06 • @LuisMendo Each program should be able to be executed with empty stdin. – Conor O'Brien Mar 28 '17 at 15:08 • @SparklePony I wouldn't quite say "absurd". – Conor O'Brien Mar 28 '17 at 15:43 ## 5 Answers # PHP, 22 programs Yeah, I get it's kind of boring.

• You could add Carrot to the list (but  outputs nothing) – user41805 Mar 28 '17 at 11:05
• And so does $ (this gets user input). So in all, in Carrot, you have 2 less programs (remove the one for$ and \) – user41805 Mar 28 '17 at 11:12
• @Kritixi Lithos Does it support 🥕? – Robert Fraser Mar 28 '17 at 11:20
• @RobertFraser All I can see is a square. But sure, it outputs it if it is the code. You can try it here – user41805 Mar 28 '17 at 11:28

It's awfully hard to come up with an answer that isn't just a string literal and outputs something other than a number...

You can trade two of $, ), or | for two of any of the chars in the nine string literals; that is, two of any of !.@Qe|~. Additionally, you can trade out the Q in the third program for H or O, and the Z for H, O, @, or {. # PowerShell, 2 programs, length 31 +!!($eefmpxy =9)

Outputs 1.
Works by setting the variable $eefmpxy to 9, encapsulating that in parens, taking the Boolean-not ! of that (which turns it to $False), then the Boolean-not of that (which turns it to $True), then casts as an integer with +, turning it to 1. That's left on the pipeline and output is implicit. 4*!$AHILOQQQTTZ

Outputs 4.
Works by initializing the variable $AHILOQQQTTZ to the default of $null, the Boolean-not ! of which is $True. That's implicitly cast to an integer 1 due to the multiplication of 4*, so the result of 4 is left on the pipeline and output is implicit. We're really limited in PowerShell for other things, as though we have plenty of pipe characters | to pipeline commands together, we only have one { and no }; too many ) for the lone (; the backtick  is used as a "line continuation marker" to interpret multiple lines as one (used for readability), but we have no linefeed to go with it; and the ~ and ^ characters are "Reserved for future use" and thus toss a syntax error when you try to use them. So, most of the characters are useless, which is a shame. While the # character starts a comment (and everything after it is completely ignored), it feels cheaty to use it that way, so I didn't include it above. # Cardinal, 1 program, length 73 %#~~~~~~~~~!!!!!+=.*449eefmpxyAHLOQQQTTZ@@@$\$I\\^{|||| ())))&..:

Cardinal can only have 1 valid program that will do anything as there is only 1 %.
