Calculating and Formatting Square Roots | Challenge

# Introduction

In this challenge, we will create a program that takes an integer input from the user and calculates its square root. The calculated square root will be printed with 3 decimal places. The output will be formatted in a specific way: it should be 30 characters wide, right-aligned, and filled with plus signs (`+`). If the result is longer than 30 characters, the width of the result should be used instead. To complete this challenge, we will utilize string methods and formatting techniques.
