Two pointer approach Java String problem solution
In many problems involving arrays or lists, we have to analyze each element of the array compared to its other elements.

To solve problems like these we usually start from the first index and loop through the array one or more times depending on our implementation. Sometimes, we also have to create a temporary array depending on our problem's requirements.
