Java Substring
Problem Statement :
Given a string, s, and two indices, start and end, print a substring consisting of all characters in the inclusive range from start to end-1. You'll find the String class' substring method helpful in completing this challenge. Input Format The first line contains a single string denoting s. The second line contains two space-separated integers denoting the respective values of start and end. Constraints 1<=|s|<=100 0<=start<end<=n String s consists of English alphabetic letters (i.e.,[a-zA-Z])only. Output Format Print the substring in the inclusive range from start to end-1.

One of the most important skills a programmer needs to learn early on is the ability to pose a problem in an abstract way. This skill is important not just for researchers but also in applied fields like software engineering and web development. You are able to solve most of a problem, except for one last subproblem, which you have posed in an abstract way as follows: Given an array consisting
