Task 1: Counter Integers Submitted by: Mohammad Sajid Anwar
You are given a string containing only lower case English letters and digits.
Write a script to replace every non-digit character with a space and then return all the distinct integers left.
Example 1
Input: $str = "the1weekly2challenge2"
Output: 1, 2
2 is appeared twice, so we count it one only.
Example 2
Input: $str = "go21od1lu5c7k"
Output: 21, 1, 5, 7
Example 3
Input: $str = "4p3e2r1l"
Output: 4, 3, 2, 1
=end comment
my @Test =
# in exp
"the1weekly2challenge2", (1, 2,),
"go21od1lu5c7k", (21, 1, 5, 7,),
"4p3e2r1l", (4, 3, 2, 1,),
"raku", (),
;
plan +@Test ÷ 2;
sub task( $a --> Array) {
( ($a ~~ m:g/\d+/ )».Str).unique.Array
}
for @Test -> $in, @exp {
is task( $in), @exp, "{@exp // @exp.^name()} <- $in.raku()";
}
done-testing;
my $str = "pqwo48957u10qt7430qr10uo105973hjf5973hj";
say qq/\nInput: \$str = "$str"\nOutput: "&task($str).join(', ')"\n/;
