# Simple algorithms and collections in Java exercises
## Introduction
This GitHub project was created to serve as a playground for practicing simple algorithms, Java Stream API and Java
collections.
## IDE Setup
This project uses Lombok Library which a java library that automatically plugs into your editor and build tools, spicing up your java.
To configure your IDE for the support of Lombok, check
out [the official documentation](https://projectlombok.org/) for detail.
## Exercises
### Java Stream API
There are exercises which introduce the Stream API usage including filtering, sorting and the output to
various formats.
1.Find 1 element on the lists which starts with given letter/word.
2.Find first/last element in the list.
3.Sort elements on the list in reverse/natural order.
4.Eliminate duplicates in the list.
### Simple algorithms
1. *Change making problem* addresses the question of finding the minimum number of coins that add up to a given amount of
money.
It is a special case of the integer knapsack problem.
### Java Math Exercises
1. Count the average of 3 integers.
2. Calculate average value of integers from a list.
3. Calculate factorial for injected integer.
4. Find n-th element from the fibonacci sequence.
### Java String Exercises
1.Check if text is a Palindrome.
2.Reverse the String.
### Java List Exercises
1. FizzBuzz exercise
2. Find 2 the smallest numbers from the list. Ignore the repetitions.
3. Find 2 elements in list whose sum is closest to zero.
4. Find first element in the list starting with letter "A" with the usage of Regex.
