[Task link] Get an integer N to create an array int[N][N] -> NxN clockwise spiral of numbers '1' separated with numbers '0'. So, the snake made with '1' cannot touch to itself. (Ex: N = 5 -> [[1,1,1,1,1],[0,0,0,0,1],[1,1,1,0,1],[1,0,0,0,1],[1,1,1,1,1]] : 1 1 1 1 1 0 0 0 0 1 1 1 1 0 1 1 0 0 0 1 1 1 1 1 1 )
[Task link] Write a function that receives an integer N -> returns an NxN array int[N][N] with numbers 1 to NxN represented as a clockwise spiral. (Ex: N = 3 -> [[1,2,3],[8,9,4],[7,6,5]] :
1 2 3
8 9 4
7 6 5 )
[Task link] The "like" system - a function that takes an array with the names of people and returns the text as shown. (Ex: ["Peter"] -> "Peter likes this", ["Alex", "Jacob", "Mark", "Max"] -> "Alex, Jacob and 2 others like this")
[Task link] Is a pangram? A function that checks: if an input string contains every letter of the alphabet [A-Z] at least once. Yes -> True, No -> False. (Ignore letter case, numbers and punctuation.)
• Isograms
[Task link] Is an isogram? A function that checks: if an input string contains no repeating letters. (Ignore letter case. The empty string is an isogram.) (Ex: "arRay" --> false)
[Task link] A function that converts a string to a new string where: if a character appears only once -> it changes to "(" in the new string, or ")" if that character appears more than once. Ignore capitalization. (Ex: "recede" --> "()()()")

[Task link] Write a function that takes 2 arrays of strings[] -> returns a sorted array (a-z order) of such strings in a1 that are substrings of a2. It must be without duplicates.
[Task link] Write a function that takes an array of strings[] and an integer k, and returns the longest string consisting of k consecutive strings. (consecutive : follow one after another without an interruption)
[Task link] Each word in the input string contains a single number - the position of the word in the result string. Write a function that will order given words to the correct string. (Ex: "is2 Thi1s T4est 3a" -> "Thi1s is2 3a T4est")
[Task link] A function takes a string -> returns it, but in every word moves the 1st letter to the end, and then add "ay" to the end of the word. (Ex: "Pig latin is cool" => "igPay atinlay siay oolcay")
