30-seconds-of-swift-code's Issues

Flip

Flip takes a function as an argument, then makes the first argument the last.

filter_non_unique

Make a function that filters out the non-unique values in a list: make a list that contains only the unique values.

dropRightWhile

Make a function that removes elements from the end of an array until the passed function returns true and returns the remaining elements in the array.

Anagram

Make a function that checks if two strings are anagrams

ex:
anagram("abcd3", "3acdb") //false
anagram("123", "456") //false

Compact

Make a function to remove "falsey" values like False, None, 0, and "".

dropRight

Make a function that returns a new array with n elements removed from the right.

ex:
dropRight(arr: [1, 2, 3]) // [1,2]
dropRight(arr: [1, 2, 3], 2) // [1]
dropRight(arr: [1, 2, 3], 42) // []

Print a string n times

Make a function that prints a string N times without using loops.

Comma separated

Make a function that accepts a list of strings and returns a single string with each element from the input list separated by commas.

array to csv

Make a function that converts a 2D array to a comma-separated values (CSV) string.

every_nth

Make a function that returns every nth element in a list: use [nth-1::nth] to create a new list that contains every nth element of the given list.

byte size

Make a function that returns the length of a string in bytes.

isSorted

Make a function that returns 1 if the array is sorted in ascending order, -1 if it is sorted in descending order, or 0 if the array is not sorted.

most frequent

Make a function that, given an array, returns the most frequent element that appears in that array.
ex:
mostFrequent(["a", 2, 4, 2, "b", 2, 3, 4, 2]) //2

Convert camel case (initial capital is used for the first letter of a word forming the second element of a closed compound, like 'PayPal' or 'iPhone') to snake case (separate words/elements with one underscore character and no spaces, like 'this_is_snake_case'). Overall, like this.

radians_to_degrees

Convert an angle from radians to degrees: multiply the number by 180, then divide the result by Pi.

Flatten

Make a function that flattens a list of lists once.
