+> Write a script to replace the character ‘e’ with ‘E’ in the string ‘Perl Weekly Challenge’. Also print the number of times the character ‘e’ is found in the string.
+
+I didn't write a script so I fail this challenge already.
+
+```
+0> my $foo = 'Perl Weekly Challenge'
+$res[0] = "Perl Weekly Challenge"
+1> $foo =~ s/e/E/g;
+$res[1] = 5
+2> $foo
+$res[2] = "PErl WEEkly ChallEngE"
+3> 
+```
+
+> Write a one-liner to solve the FizzBuzz problem and print the numbers 1 through 20. However, any number divisible by 3 should be replaced by the word ‘fizz’ and any divisible by 5 by the word ‘buzz’. Those numbers that are both divisible by 3 and 5 become ‘fizzbuzz’.
+
+I don't remember where I saw this, but it is my favourite Perl5 FizzBuzz:
+
+```
+4> { no strict; no warnings; map { (fizz)[$_%3].(buzz)[$_%5]||$_ } 1..20 }
+$res[4] = [
+    [0]  1,
+    [1]  2,
+    [2]  "fizz",
+    [3]  4,
+    [4]  "buzz",
+    [5]  "fizz",
+    [6]  7,
+    [7]  8,
+    [8]  "fizz",
+    [9]  "buzz",
+    [10] 11,
+    [11] "fizz",
+    [12] 13,
+    [13] 14,
+    [14] "fizzbuzz",
+    [15] 16,
+    [16] 17,
+    [17] "fizz",
+    [18] 19,
+    [19] "buzz"
+]
+```
+
+Since I didn't write that myself I also fail the second part of the challenge. Not going well. Let's see...
+
+```
+$ perl -MAcme::FizzBuzz -e '1' | head -n 20 | tr '[:upper:]' '[:lower:]'
+1
+2
+fizz
+4
+buzz
+fizz
+7
+8
+fizz
+buzz
+11
+fizz
+13
+14
+fizzbuzz
+16
+17
+fizz
+19
+buzz
+```
+
+ There!
