It normally start with two pointers or indices called *left* and *right* which will start from 0. 2. increment the *right* as long as the necessary condition is satisfied 3. If a condition is not satisfied, you start increasing *left*. you might also do clean up tasks when left is moved --- tags: #algorithm
