This is to be done in Python. Please assist in anyway. If something is not clear, i will provide further explanation. Be sure to use the test case to match the output.

psuedocode for googleMap and googleReduce:

Test with the following:

1. Introduction The objective of the assignment is to create a prototype of Google's Map Reduce in Python 3. The prototype is going to run all map and reduce jobs serially (one after another in a single thread. You should code a single class GoogleMapReduce in a file GoogleMapReduce.py The class should have the following functionality: Constructor arguments: none function googleMap arguments: input2Dtuple, ndices, valuelndices, googleMapper function googleReduce arguments: googleReducer function getMappedCopy arguments: none function getGroupedByCopy arguments: none If in doubt about functionality: 1) consult Google's publication 2) analyze the use case, its input, output, and debug printouts 1.
