Implement a Fibonnaci Sequence in three different ways:
Recursively
Dynamically (Using Memoization to store results)
Iteratively

- Algorithm / python

Given a string, write a function that uses recursion to output a list of all the possible permutations of that string.

- Algorithm / Data Structure / python

This interview question requires you to reverse a string using recursion. Make sure to think of the base case here.

- Algorithm

The first is when recursion is used as a technique in which a function makes one or more calls to itself. The second is when a data structure uses smaller instances of the exact same type of data structure when it represents itself. Both of these instances are use cases of recursion.

- Algorithm / Data Structure / python

Given a string of opening and closing parentheses, check whether itâ€™s balanced. We have 3 types of parentheses: round brackets: (), square brackets: [], and curly brackets: {}.

- Algorithm / python

Given a string,determine if it is compressed of all unique characters. For example, the string 'abcde' has all unique characters and should return True.

- Algorithm / python

Given a string in the form 'AAAABBBBCCCCCDDEEEE' compress it to become 'A4B4C5D2E4'. For this problem, you can falsely "compress" strings of single or double letters.

- Algorithm / Data Structure / python

Given an array of integers (positive and negative) find the largest continuous sum.

- Algorithm / Data Structure / python

Consider an array of non-negative integers. A second array is formed by shuffling the elements of the first array and deleting a random element. Given these two arrays, find which element is missing in the second array.
