Introduction To Java

JAVA was developed by James Gosling at Sun Microsystems Inc in the year 1991, later acquired by Oracle Corporation. It is a simple programming language. Java makes writing, compiling, and debugging programming easy. It helps to create reusable code and modular programs.

Java is a class-based, object-oriented programming language and is designed to have as few implementation dependencies as possible. A general-purpose programming language made for developers to write once run anywhere that is compiled Java code can run on all platforms that support Java. Java applications are compiled to byte code that can run on any Java Virtual Machine. The syntax of Java is similar to c/c++.

Objective

Java’s BigDecimal class can handle arbitrary-precision signed decimal numbers. Let’s test your knowledge of them!

Given an array, , of  real number strings, sort them in descending order — but wait, there’s more! Each number must be printed in the exact same format as it was read from stdin, meaning that  is printed as , and  is printed as . If two numbers represent numerically equivalent values (e.g., ), then they must be listed in the same order as they were received as input).

Complete the code in the unlocked section of the editor below. You must rearrange array ‘s elements according to the instructions above.

Input Format

The first line consists of a single integer, , denoting the number of integer strings.
Each line  of the  subsequent lines contains a real number denoting the value of .

Constraints

• Each  has at most  digits.

Output Format

Locked stub code in the editor will print the contents of array  to stdout. You are only responsible for reordering the array’s elements.
