• Challenge 17 ⭐

  Using different methods to repeat a string

• Challenge 18 ⭐

  Truncate a string if it is longer than the given maximum string length. Return the truncated string with a ... ending. However, if the given maximum string length num is less than or equal to 3, then the addition of the three dots does not add to the string length in determining the truncated string.

• Challenge 19 ⭐

  Write a function that splits an array (first auguments) into groups the length
  of size (second argument) and return them as a two-dimensional array.

• Challenge 20 ⭐

  Return the remaining elements of an array after chopping off n elements from the head.

• Challenge 21 ⭐⭐

  Count repeating letters, string will not contain numbers or submols only letters.

• Challenge 22 ⭐

  Mutations: return true if the first element of the array contains all of the letters of the string in the second element of the array.

• Challenge 23 ⭐

  Remove all flasy values from an array.

• Challenge 24 ⭐⭐

  Be provided with an initial array (the first argument in the destroyer function), followed by one or more arguments. Remove all elements from the initial array that are of the same value as these arguments.

• Challenge 25 ⭐⭐⭐ LeetCode -> 001

  Given an array of integers, return indices of the two numbers such that they add up to a specific target. the first index should smaller than second

• Challenge 26 ⭐

  Return the lowest index at which a value should be inserted into an array once it has been sorted. The returned value should be a number.

• Challenge 27 ⭐

  One of the simplest and most widely known ciphers is Caesar cipher, also known as shift cipher. In a shift cipher the meanings of the letters are shifted by some set amoutn. A common modern use is the ROT13 cipher, where the values of the letters are shifted by 13 places. Thus A<->N, B<->Oand so on. Reference: ASCII-Table

• Challenge 28 ⭐

  We will pass an array of two numbers. Return the sum of those two numbers and all numbers between them. The lowest number will not always come first.

• Challenge 29 ⭐

  Compare two arrays and return a new array with any items only found in one of the two given arrays, but not both. In other words, return the symmetric difference of the two arrays.

• Challenge 30 ⭐⭐

  Convert the given number into a romon numeral. All roman numerals answers should be provided in upper-case.
