DAY 19: ALGORITHMS IN SWIFT

Problem Source Credit - Swift Coding Challenges by Paul Hudson (Creator of Hacking With Swift)

Today we're dealing with string permutations. Permutations are defined as any rearrangement of the letters of a word. Our problem states, "Write a function that prints all possible permutations of a given input string". The string "tba" would be a permutation of the word "bat". In this problem we're dealing with a recursive function to get to the deepest root of the word and scaling back up to spell out all possible rearrangements of the word.

Please comment below if you have any solutions to this problem and/or if you found this video helpful.

CALL TO ACTION: Please share with anyone that's going through coding interviews as this video will be valuable to them.
