Write a program in PYTHON that will take an input file called input.txt which will contain a Java program and parse it and output an annotated version.

Your program will track the nesting depth of the braces of the input file and will output an annotated version of the file

. Your final program will 1. List the nesting depth of curly braces 2. Ignore braces inside quotes or comments Use Python Assume that all quoted strings begin and end on the same line. Sample INPUT: -------------------

Sample INPUT import blah; class Foo void Foo0 System.out.println("braces are fun! "); // ignored if (condition) // also ignored: { // as is this: ) //end of program Sample annotated OUTPUT: 0 import blah 0 class Foo 1 void Foo0 2 System.out.println("braces are fun! "): /ignored 2if (condition) /l also ignored int a 1 : // as is this: 0 // end of program
