+Task 1: Goat Latin
+
+Submitted by: [57]Mohammad Sajid Anwar
+     __________________________________________________________________
+
+   You are given a sentence, $sentance.
+
+   Write a script to convert the given sentence to Goat Latin, a made up
+   language similar to Pig Latin.
+
+   Rules for Goat Latin:
+1) If a word begins with a vowel ("a", "e", "i", "o", "u"), append
+   "ma" to the end of the word.
+2) If a word begins with consonant i.e. not a vowel, remove first
+   letter and append it to the end then add "ma".
+3) Add letter "a" to the end of first word in the sentence, "aa" to
+   the second word, etc etc.
+
+Example 1
+
+Input: $sentence = "I love Perl"
+Output: "Imaa ovelmaaa erlPmaaaa"
+
+Example 2
+
+Input: $sentence = "Perl and Raku are friends"
+Output: "erlPmaa andmaaa akuRmaaaa aremaaaaa riendsfmaaaaaa"
+
+Example 3
+
+Input: $sentence = "The Weekly Challenge"
+Output: "heTmaa eeklyWmaaa hallengeCmaaaa"

+Task 2: Bus Route
+
+Submitted by: [58]Peter Campbell Smith
+     __________________________________________________________________
+
+   Several bus routes start from a bus stop near my home, and go to the
+   same stop in town. They each run to a set timetable, but they take
+   different times to get into town.
+
+   Write a script to find the times - if any - I should let one bus leave
+   and catch a strictly later one in order to get into town strictly
+   sooner.
+
+   An input timetable consists of the service interval, the offset within
+   the hour, and the duration of the trip.
+
+Example 1
+
+Input: [ [12, 11, 41], [15, 5, 35] ]
+Output: [36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47]
+
+Route 1 leaves every 12 minutes, starting at 11 minutes past the hour (so 11, 23
+, ...) and takes 41 minutes. Route 2 leaves every 15 minutes, starting at 5 minu
+tes past (5, 20, ...) and takes 35 minutes.
+
+At 45 minutes past the hour I could take the route 1 bus at 47 past the hour, ar
+riving at 28 minutes past the following hour, but if I wait for the route 2 bus
+at 50 past I will get to town sooner, at 25 minutes past the next hour.
+
+Example 2
+
+Input: [ [[12, 3, 41], [15, 9, 35], [30, 5, 25] ]
+Output: [ 0, 1, 2, 3, 25, 26, 27, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51
+, 55, 56, 57, 58, 59 ]
+     __________________________________________________________________
+
+   Last date to submit the solution 23:59 (UK Time) Sunday 23rd June 2024.
