N'th

From Rosetta Code
Revision as of 04:11, 17 March 2014 by rosettacode>TimToady (→‎{{Header|Perl 6}}: add unicodey version)
N'th is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

Write a function/method/subroutine/... that when given an integer greater than or equal to zero returns a string of the number followed by an apostrophe then the ordinal suffix.
Example returns would include 1'st 2'nd 3'rd 11'th 1001'st

Task

Use your routine to show here the output for at least the following (inclusive) ranges of integer inputs: 0..25, 250..265, 1000..1025

D

Translation of: Python

<lang d>import std.stdio, std.string, std.range, std.algorithm;

string nth(in uint n) pure {

   static immutable suffix = "th st nd rd th th th th th th".split;
   return "%d'%s".format(n, (n % 100 <= 10 || n % 100 > 20) ?
                            suffix[n % 10] : "th");

}

void main() {

   foreach (r; [iota(26), iota(250, 266), iota(1000, 1026)])
       writefln("%-(%s %)", r.map!nth);

}</lang>

Output:
0'th 1'st 2'nd 3'rd 4'th 5'th 6'th 7'th 8'th 9'th 10'th 11'th 12'th 13'th 14'th 15'th 16'th 17'th 18'th 19'th 20'th 21'st 22'nd 23'rd 24'th 25'th

1000'th 1001'st 1002'nd 1003'rd 1004'th 1005'th 1006'th 1007'th 1008'th 1009'th 1010'th 1011'th 1012'th 1013'th 1014'th 1015'th 1016'th 1017'th 1018'th 1019'th 1020'th 1021'st 1022'nd 1023'rd 1024'th 1025'th

250'th 251'st 252'nd 253'rd 254'th 255'th 256'th 257'th 258'th 259'th 260'th 261'st 262'nd 263'rd 264'th 265'th

Note the cute colorization caused by the interaction between this task's imposition of the quote character and this wiki's syntax support.

Perl 6

(Spurious apostrophes intentionally omitted.) <lang perl6>my %irregulars = <1 st 2 nd 3 rd>, (11..13 X=> 'th');

sub nth ($n) { $n ~ ( %irregulars{$n % 100} // %irregulars{$n % 10} // 'th' ) }

say .list».&nth for [^26], [250..265], [1000..1025];</lang>

Output:
0th 1st 2nd 3rd 4th 5th 6th 7th 8th 9th 10th 11th 12th 13th 14th 15th 16th 17th 18th 19th 20th 21st 22nd 23rd 24th 25th
250th 251st 252nd 253rd 254th 255th 256th 257th 258th 259th 260th 261st 262nd 263rd 264th 265th
1000th 1001st 1002nd 1003rd 1004th 1005th 1006th 1007th 1008th 1009th 1010th 1011th 1012th 1013th 1014th 1015th 1016th 1017th 1018th 1019th 1020th 1021st 1022nd 1023rd 1024th 1025th

If you want to get Unicodally fancy, use this version instead: <lang perl6>my %irregulars = <1 ˢᵗ 2 ⁿᵈ 3 ʳᵈ>, (11..13 X=> 'ᵗʰ');

sub nth ($n) { $n ~ ( %irregulars{$n % 100} // %irregulars{$n % 10} // 'ᵗʰ' ) }

say .list».&nth for [^26], [250..265], [1000..1025];</lang>

Output:

0ᵗʰ 1ˢᵗ 2ⁿᵈ 3ʳᵈ 4ᵗʰ 5ᵗʰ 6ᵗʰ 7ᵗʰ 8ᵗʰ 9ᵗʰ 10ᵗʰ 11ᵗʰ 12ᵗʰ 13ᵗʰ 14ᵗʰ 15ᵗʰ 16ᵗʰ 17ᵗʰ 18ᵗʰ 19ᵗʰ 20ᵗʰ 21ˢᵗ 22ⁿᵈ 23ʳᵈ 24ᵗʰ 25ᵗʰ
