Puny Computer Problem¶
Build a compressed sparse row matrix from this file of text

- row i of the matrix represents row i of the file.
- column j of the matrix represents the jth unique word observed in the file.
- element ij represents the number of times word j was observed in line i.
There’s a catch..
Your computer is so puny that it can’t fit the entire file into memory at one time. It can fit each line into memory, just not the entire file.
