Get started with one-dimensional arrays and array variables, then try out five algorithms for searching and sorting arrays in your Java programs ...

//Given an array of integers A sorted in non-decreasing order, return an array of the squares of each number, also in sorted non-decreasing order.

//Given a sorted array nums, remove the duplicates in-place such that each element appear only once and return the new length. //Do not allocate extra space for another array, you must do this by ...

Data structures and algorithms in Java, Part 2 introduced a variety of techniques for searching and sorting one-dimensional arrays, which are the simplest arrays.
