Python Guru needed (Data Structures & Algorithm questions - Technical Interviews)

I've a list of some 50-60 questions that are generally asked in technical interviews. Some are easy like : -> "reverse a string in place" and some are difficult example like: -> implement code that checks if given Java code has proper braces ** Send me a Private Message to get the list of question. Your TASKS are: ** 1. do research (Google, StackOverflow etc) and find answers to all these questions (in Python). If you can't find an answer, then you'll have to code it (in PYTHON ) yourself. ** 2 . when you find code (or write your own code), please add comments and explaining algorithm in great detail. For example, if you go here: [login to view URL] go to PYTHON version of the code. You'll see that author has commented every step of the algorithm in code so it is easy to understand and explain in an interview.
