python programming:

Write a PYTHON program 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.

Assume that all quoted strings begin and end on the same line.

Sample INPUT import blah; class Foo void Foo(0 System.out.println("braces are fun! fissf");ignored if (condition) /l also ignored: { int a-1: // as is this: /lend of program Sample annotated OUTPUT 0 import blah; 0 class Foo 1 void FooO 2 System.out.println("braces are fun! ii);/ignored 2if (condition) // also ignored: f int a=1 3 / as is this: ) 0 // end of program
